Barnes' Notes on the Bible

Search me, O God - The word "search" here is the same as in Psalm 139:1. See the notes at that verse. The psalmist had stated the fact that it is a characteristic of God that he "does" search the heart; and he here prays that God "would" exercise that power in relation to himself; that as God could know all that there is within the heart, he would examine him with the closest scrutiny, so that he might be under no delusion or self-deception; that he might not indulge in any false hopes; that he might not cherish any improper feelings or desires. The prayer denotes great "sincerity" on the part of the psalmist. It indicates also self-distrust. It is an expression of what all must feel who have any just views of themselves - that the heart is very corrupt; that we are liable to deceive ourselves; and that the most thorough search "should" be made that we be "not" deceived and lost.

And know my heart - Know or see all that is within it.

Try me - As metal is tried or proved that is put to a "test" to learn what it is. The trial here is that which would result from the divine inspection of his heart.

And know my thoughts - See what they are. The word rendered "thoughts" occurs only in one other place, Psalm 94:19. The idea is, Search me thoroughly; examine not merely my outward conduct, but what I think about; what are my purposes; what passes through my mind; what occupies my imagination and my memory; what secures my affections and controls my will. He must be a very sincere man who prays that God will search his thoughts, for there are few who would be willing that their fellow-men, even their best friends, should know all that they are thinking about.


Clarke's Commentary on the Bible

Search me, O God - Investigate my conduct, examine my heart, put me to the test, and entwine my thoughts.


Gill's Exposition of the Entire Bible

Search me, O God, and know my heart,.... He had searched him, and knew his heart thoroughly;

try me, and know my thoughts; he had tried him, and knew every thought in him, Psalm 139:1. This therefore is not said for the sake of God; who, though he is the trier of hearts, and the searcher of the reins, is indeed a discerner of the thoughts and intents of the heart at once, and knows immediately what is in man; and needs no testimony of him, nor to make use of any means in order to know him and what is within him: but David said this for his own sake, that God would search and make known to him what was in his heart, and try him by his word, as gold is tried in the fire; or by anything difficult and self-denying, as he tried Abraham; or by any afflictive providence; or in any way he thought fit to make him acquainted thoroughly with himself. His sense is this, that if he knew his own heart and thoughts, and the inward frame and disposition of his soul, it was as he had expressed it; that he was grieved with sinners, and hated those that hated the Lord, even with a perfect hatred, and reckoned them as his enemies; but if it was otherwise, he desired to be searched and tried thoroughly, that it might be discovered: and he might say this also on account of others, who charged him falsely with things he was not conscious of; that never entered into his thoughts, and his heart knew nothing of, and could not accuse him with; and therefore he appeals to the heart searching God, that he would so lay open things that his integrity and innocence might appear to all; see Genesis 22:1.


Keil and Delitzsch Biblical Commentary on the Old Testament

He sees in them the danger which threatens himself, and prays God not to give him over to the judgment of self-delusion, but to lay bare the true state of his soul. The fact "Thou hast searched me," which the beginning of the Psalm confesses, is here turned into a petitioning "search me." Instead of רעים in Psalm 139:17, the poet here says שׂרעפּים, which signifies branches (Ezekiel 31:5) and branchings of the act of thinking (thoughts and cares, Psalm 94:19). The Resh is epenthetic, for the first form is שׂעפּים, Job 4:13; Job 20:2. The poet thus sets the very ground and life of his heart, with all its outward manifestations, in the light of the divine omniscience. And in Psalm 139:24 he prays that God would see whether any דּרך־עצב cleaves to him (בּי as in 1 Samuel 25:24), by which is not meant "a way of idols" (Rosenm׬ller, Gesenius, and Maurer), after Isaiah 48:5, since an inclination towards, or even apostasy to, heathenism cannot be an unknown sin; nor to a man like the writer of this Psalm is heathenism any power of temptation. דוך בּצע (Grהtz) might more readily be admissible, but דוך עצב is a more comprehensive notion, and one more in accordance with this closing petition. The poet gives this name to the way that leads to the pain, torture, viz., of the inward and outward punishments of sin; and, on the other hand, the way along which he wishes to be guided he calls דּרך עולם, the way of endless continuance (lxx, Vulgate, Luther), not the way of the former times, after Jeremiah 6:16 (Maurer, Olshausen), which thus by itself is ambiguous (as becomes evident from Job 22:15; Jeremiah 18:15), and also does not furnish any direct antithesis. The "everlasting way" is the way of God (Psalm 27:11), the way of the righteous, which stands fast for ever and shall not "perish" (Psalm 1:6).

Matthew Henry's Concise Commentary

139:17-24 God's counsels concerning us and our welfare are deep, such as cannot be known. We cannot think how many mercies we have received from him. It would help to keep us in the fear of the Lord all the day long, if, when we wake in the morning, our first thoughts were of him: and how shall we admire and bless our God for his precious salvation, when we awake in the world of glory! Surely we ought not to use our members and senses, which are so curiously fashioned, as instruments of unrighteousness unto sin. But our immortal and rational souls are a still more noble work and gift of God. Yet if it were not for his precious thoughts of love to us, our reason and our living for ever would, through our sins, prove the occasion of our eternal misery. How should we then delight to meditate on God's love to sinners in Jesus Christ, the sum of which exceeds all reckoning! Sin is hated, and sinners lamented, by all who fear the Lord. Yet while we shun them we should pray for them; with God their conversion and salvation are possible. As the Lord knows us thoroughly, and we are strangers to ourselves, we should earnestly desire and pray to be searched and proved by his word and Spirit. if there be any wicked way in me, let me see it; and do thou root it out of me. The way of godliness is pleasing to God, and profitable to us; and will end in everlasting life. It is the good old way. All the saints desire to be kept and led in this way, that they may not miss it, turn out of it, or tire in it.


Matthew Henry's Whole Bible Commentary

Verses 17-24

Here the psalmist makes application of the doctrine of God's omniscience, divers ways.

I. He acknowledges, with wonder and thankfulness, the care God had taken of him all his days, v. 17, 18. God, who knew him, thought of him, and his thoughts towards him were thoughts of love, thought of good, and not of evil, Jer. 29:11. God's omniscience, which might justly have watched over us to do us hurt, has been employed for us, and has watched over us to do us good, Jer. 31:28. God's counsels concerning us and our welfare have been, 1. Precious to admiration: How precious are they! They are deep in themselves, such as cannot possibly be fathomed and comprehended. Providence has had a vast reach in its dispensations concerning us, and has brought things about for our good quite beyond our contrivance and foresight. They are dear to us; we must think of them with a great deal of reverence, and yet with pleasure and thankfulness. Our thoughts concerning God must be delightful to us, above any other thoughts. 2. Numerous to admiration: How great is the sum of them! We cannot conceive how many God's kind counsels have been concerning us, how many good turns he has done us, and what variety of mercies we have received from him. If we would count them, the heads of them, much more the particulars of them, they are more in number than the sand, and yet every one great and very considerable, Ps. 40:5. We cannot conceive the multitude of God's compassions, which are all new every morning. 3. Constant at all times: "When I awake, every morning, I am still with thee, under thy eye and care, safe and easy under thy protection." This bespeaks also the continual devout sense David had of the eye of God upon him: When I awake I am with thee, in my thoughts; and it would help to keep us in the fear of the Lord all the day long if, when we awake in the morning, our first thoughts were of him and we did then set him before us.

II. He concludes from this doctrine that ruin will certainly be the end of sinners. God knows all the wickedness of the wicked, and therefore he will reckon for it: "Surely thou wilt slay the wicked, O God! for all their wickedness is open before thee, however it may be artfully disguised and coloured over, to hide it from the eye of the world. However thou suffer them to prosper for a while, surely thou wilt slay them at last." Now observe, 1. The reason why God will punish them, because they daringly affront him and set him at defiance (v. 20): They speak against thee wickedly; they set their mouth against the heavens (Ps. 73:9), and shall be called to account for the hard speeches they have spoken against him, Jude 15. They are his enemies, and declare their enmity by taking his name in vain, as we show our contempt of a man if we make a by-word of his name, and never mention him but in a way of jest and banter. Those that profane the sacred forms of swearing or praying by using them in an impertinent irreverent manner take God's name in vain, and thereby show themselves enemies to him. Some make it to be a description of hypocrites: "They speak of thee for mischief; they talk of God, pretending to piety, but it is with some ill design, for a cloak of maliciousness; and, being enemies to God, while they pretend friendship, they take his name in vain; they swear falsely." 2. The use David makes of this prospect which he has of the ruin of the wicked. (1.) He defies them: "Depart from me, you bloody men; you shall not debauch me, for I will not admit your friendship nor have fellowship with you; and you cannot destroy me, for, being under God's protection, he shall force you to depart from me." (2.) He detests them (v. 21, 22): "Lord, thou knowest the heart, and canst witness for me; do not I hate those that hate thee, and for that reason, because they hate thee? I hate them because I love thee, and hate to see such affronts and indignities put upon thy blessed name. Am not I grieved with those that rise up against thee, grieved to see their rebellion and to foresee their ruin, which it will certainly end in?" Note, Sin is hated, and sinners are lamented, by all that fear God. "I hate them" (that is, "I hate the work of them that turn aside," as he explains himself, Ps. 101:3) "with a sincere and perfect hatred; I count those that are enemies to God as enemies to me, and will not have any intimacy with them," Ps. 69:8.

III. He appeals to God concerning his sincerity, v. 23, 24. 1. He desires that as far as he was in the wrong God would discover it to him. Those that are upright can take comfort in God's omniscience as a witness of their uprightness, and can with a humble confidence beg of him to search and try them, to discover them to themselves (for a good man desires to know the worst of himself) and to discover them to others. He that means honestly could wish he had a window in his breast that any man may look into his heart: "Lord, I hope I am not in a wicked way, but see if there be any wicked way in me, any corrupt inclination remaining; let me see it; and root it out of me, for I do not allow it." 2. He desires that, as far as he was in the right, he might be forwarded in it, which he that knows the heart knows how to do effectually: Lead me in the way everlasting. Note, (1.) The way of godliness is an everlasting way; it is everlastingly true and good, pleasing to God and profitable to us, and will end in everlasting life. It is the way of antiquity (so some), the good old way. (2.) All the saints desire to be kept and led in this way, that they may not miss it, turn out of it, nor tire in it.
