Matthew Henry and continuators on Psalms 119:163

163 I hate and abhor lying: but thy law do I love.

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. vi. 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.
