| Barnes' Notes on the Bible My soul breaketh - This word means to break; to crush; to break in pieces by scraping, rubbing, or grating. The idea would seem to be, not that he was crushed as by a single blow, but that his soul - his strength - was worn away by little and little. The desire to know more of the commands of God acted continually on him, exhausting his strength, and overcoming him. He so longed for God that, in our language, "it wore upon him" - as any ungratified desire does. It was not the possession of the knowledge of God that exhausted him; it was the intenseness of his desire that he might know more of God. For the longing - For the earnest desire. That it hath unto thy judgments at all times - Thy law; thy commands. This was a constant feeling. It was not fitful or spasmodic. It was the steady, habitual state of the soul on the subject. He had never seen enough of the beauty and glory of the law of God to feel that all the needs of his nature were satisfied, or that he could see and know no more; he had seen and felt enough to excite in him an ardent desire to be made fully acquainted with all that there is in the law of God. Compare the notes at Psalm 17:15.
Clarke's Commentary on the BibleMy soul breaketh - We have a similar expression: It broke my heart, That is heart-breaking, She died of a broken heart. It expresses excessive longing, grievous disappointment, hopeless love, accumulated sorrow. By this we may see the hungering and thirsting which the psalmist had after righteousness, often mingled with much despondency.
Gill's Exposition of the Entire BibleMy soul breaketh for the longing,.... His heart was just ready to break, and his soul fainted; he was ready to die, through a vehement desire of enjoying the object longed for, after mentioned; "hope deferred makes the heart sick", Proverbs 13:1; the phrase is expressive of the greatness, vehemence, and eagerness of his mind after the thing he desired, which follows: that it hath unto thy judgments at all times; not the judgments of God on wicked men, though these are desirable for the glorifying of his justice; nor his dark dispensations of providence, though good men cannot but desire and long for the time when these judgments shall be made manifest: but rather the righteous laws and precepts of God are designed, which he desired to have a more perfect knowledge of, and yield a more constant obedience unto; or, best of all, the doctrines of grace and righteousness, that should be more clearly revealed in the times of the Messiah; who was to set judgment in the earth, his Gospel; and to bring in everlasting righteousness, and glorify the justice of God; than which nothing was more earnestly and importunately wished and longed for by Old Testament saints; see Psalm 119:81.
Geneva Study BibleMy soul breaketh for the longing that it hath unto thy judgments at all times.
Wesley's Notes 119:20 Breaketh - Faints, as it frequently does, when a thing vehemently desired is delayed. Judgments - To a more sound knowledge and serious practice of them.
Matthew Henry's Concise Commentary119:17-24 If God deals in strict justice with us, we all perish. We ought to spend our lives in his service; we shall find true life in keeping his word. Those that would see the wondrous things of God's law and gospel, must beg him to give them understanding, by the light of his Spirit. Believers feel themselves strangers on earth; they fear missing their way, and losing comfort by erring from God's commandments. Every sanctified soul hungers after the word of God, as food which there is no living without. There is something of pride at the bottom of every wilful sin. God can silence lying lips; reproach and contempt may humble and do us good, and then they shall be removed. Do we find the weight of the cross is above that we are able to bear? He that bore it for us will enable us to bear it; upheld by him we cannot sink. It is sad when those who should protect the innocent, are their betrayers. The psalmist went on in duty, and he found comfort in the word of God. The comforts of the word of God are most pleasant to a gracious soul, when other comforts are made bitter; and those that would have God's testimonies to be their delight, must be advised by them. May the Lord direct us in exercising repentance of sin, and faith in Christ.
Matthew Henry's Whole Bible CommentaryVerse 20 David had prayed that God would open his eyes (v. 18) and open the law (v. 19); now here he pleads the earnestness of his desire for knowledge and grace, for it is the fervent prayer that avails much. 1. His desire was importunate: My soul breaketh for the longing it hath to thy judgments, or (as some read it) "It is taken up, and wholly employed, in longing for thy judgments; the whole stream of its desires runs in this channel. I shall think myself quite broken and undone if I want the word of God, the direction, converse, and comfort of it." 2. It was constant-at all times. It was not now and then, in a good humour, that he was so fond of the word of God; but it is the habitual temper of every sanctified soul to hunger after the word of God as its necessary food, which there is no living without. |
