Psalms 119:43

And take not the word of truth utterly out of my mouth
The Scriptures, which are by divine inspiration, come from the God of truth, contain nothing but truth in them, and are called "the Scriptures of truth", ( Daniel 10:21 ) . Or the Gospel, which is often so called, ( Ephesians 1:13 ) ( James 1:18 ) ; This comes from God, who cannot lie, and is a declaration of his mind and will concerning the salvation of men; in which Christ, who is the truth, is concerned, being the author, preacher, and substance of it; into which the Spirit of truth leads men, and makes it useful and effectual; which has many eminent and important truths in it, and nothing but truth, and stands opposed to the law, which is typical and shadowy, and to everything that is a falsehood and a lie. This the psalmist desires might not be taken out of his mouth, but kept in it as a sweet morsel there, rolled under his tongue; be eaten and fed upon by him, and be the rejoicing of his heart. Or his sense is, that he might not be left under a temptation to conceal, drop, or deny the word of truth, or be ashamed to own and confess it before men; but at all times, and upon all occasions, publicly declare it, and his faith in it: at least he desires that it might not "utterly" cease from him, or be wholly neglected by him, and he entirely apostatize. Some join the word rendered "utterly", and which signifies "exceedingly", with "the word of truth", thus: "take not out of my mouth the word of truth, [which is] exceedingly [so]"; that is, exceedingly true, to the highest degree ^F5;

for I have hoped in thy judgments;
or, "have waited for thy judgments" {f}: either the judgments of God upon sinners, especially on apostates, which he knew would be very sore and severe, their last estate being worse than the first; or rather the last judgment, when those that confess Christ and his truths shall be confessed by him; and those that deny him and his Gospel will be denied by him: though it may be best of all to understand it of the word of God, and the doctrines of it, which the psalmist had an exceeding great regard unto, hoped, waited, and even longed for; see ( Psalms 119:20 ) .
