| Barnes' Notes on the Bible I hate and abhor lying - The mention of lying here particularly seems to have been suggested by the necessity, from the structure of the psalm, of finding some word at the beginning of the verse which commenced with the letter Schin. At the same time, it is an illustration of the nature of piety, and doubtless there had been numerous occasions in the life of the psalmist when he had seen and experienced the effects of falsehood. This sin, therefore, might occur to him as readily as any other. It is unnecessary to say that religion "forbids" this sin in all its forms. But thy law do I love - Particularly here the law which forbids lying. The psalmist was conscious, as every good man must be, that he truly loved that pure law which forbids falsehood in all its forms.
Clarke's Commentary on the BibleI-- abhor lying - Perhaps they might have made the confessions which the Chaldeans required, and by mental reservation have kept an inward firm adherence to their creed; but this, in the sight of the God of truth, must have been lying; and at such a sacrifice they would not purchase their enlargement, even from their captivity.
Gill's Exposition of the Entire BibleI hate and abhor lying,.... The sin of lying in common conversation, which owes its rise to Satan, the father of lies; is common to human nature, though very dishonourable to it; exceeding unbecoming a professor of religion; and was greatly hated by David, as it ought to be by all good men, Psalm 101:7. Or "falsehood" (k); false doctrine; everything contrary to the truth of the word of God, with all false worship, superstition, and idolatry; and this may the rather be thought to be designed, since the law or doctrine of God is opposed to it in the next clause; but thy law do I love; because holy, just, and true; he being a regenerate man, and having it written on his heart, he loved both the precepts of the law and the doctrines of the Gospel: or, "thy doctrine"; the doctrine concerning God, his mind and will, his grace and love; see Psalm 119:97.

Geneva Study BibleI hate and abhor lying: but thy law do I love.
Jamieson-Fausset-Brown Bible Commentary163. lying-that is, as in Ps 119:29, unfaithfulness to the covenant of God with His people; apostasy.
Matthew Henry's Concise Commentary119:161-168 Those whose hearts stand in awe of God's word, will rather endure the wrath of man, than break the law of God. By the word of God we are unspeakable gainers. Every man hates to have a lie told him, but we should more hate telling a lie; by the latter we give an affront to God. The more we see the beauty of truth, the more we shall see the hateful deformity of a lie. We are to praise God even for afflictions; through grace we get good from them. Those that love the world have great vexation, for it does not answer what they expect; those that love God's word have great peace, for it outdoes what they expect. Those in whom this holy love reigns, will not perplex themselves with needless scruples, or take offence at their brethren. A good hope of salvation will engage the heart in doing the commandments. And our love to the word of God must subdue our lusts, and root out carnal affections: we must make heart work of it, or we make nothing of it. We must keep the commandments of God by obedience to them, and his promises by reliance on them. God's eye is on us at all times; this should make us very careful to keep his commandments.
Matthew Henry's Whole Bible CommentaryVerse 163 Love and hatred are the leading affections of the soul; if those be fixed aright, the rest move accordingly. Here we have them fixed aright in David. 1. He had a rooted antipathy to sin; he could not endure to think of it: I hate and abhor lying, which may be taken for all sin, inasmuch as by it we deal treacherously and perfidiously with God and put a cheat upon ourselves. Hypocrisy is lying; false doctrine is lying; breach of faith is lying. Lying, in commerce or conversation, is a sin which every good man hates and abhors, hates and doubly hates, because of the seven things which the Lord hates one is a lying tongue and another is a false witness that speaks lies, Prov. 6:16. Every man hates to have a lie told him; but we should more hate telling a lie because by the former we only receive an affront from men, by the latter we give an affront to God. 2. He had a rooted affection to the word of God: Thy law do I love. And therefore he abhorred lying, for lying is contrary to the whole law of God; and the reason why he loved the law of God was because of the truth of it. The more we see of the amiable beauty of truth the more we shall see of the detestable deformity of a lie. |
