(18) They shall withal be fitted in thy lips.--Rather, if they be established (dwell constantly) upon thy lips. They are to be as a watch, and "keep the door of his lips" against sin (Psalm 141:3), to teach him what to say in difficulty (Mark 13:11), how to speak without fear even before kings (Psalm 119:46); by them the "praises of God" will ever be in his mouth (Psalm 149:6).

Verse 18. - This verse gives the reason for the previous exhortation. It is a pleasant thing if thou keep them within thee; in thy mind and memory (comp. Proverbs 18:8; Proverbs 20:27). Thus Psalm 147:1, "It is good to sing praises unto our God; for it is pleasant, and praise is comely." They shall withal be fitted in thy lips. This rendering hardly suits the hortatory nature of the introduction. It is better to take the clause in the optative, as Delitzsch, Ewald, Nowack, and ethers: "Let them abide altogether upon thy lips;" i.e. be not ashamed to profess them openly, let them regulate thy words, teach thee wisdom and discretion. Septuagint, "And if thou admit them to thy heart, they shall likewise gladden thee on thy lips."

22:17-21. To these words, to this knowledge, the ear must be bowed down, and the heart applied by faith and love. To live a life of delight in God and dependence on him, is the foundation of all practical religion. The way to know the certainty of the word of truth, is to make conscience of our duty. 22,23. He that robs and oppresses the poor, does so at his peril. And if men will not appear for them, God will. 24,25. Our corrupt hearts have so much tinder in them, that it is dangerous to have to do with those that throw about the sparks of their passion.For it is a pleasant thing if thou keep them within thee,.... Or, "in thy belly" (a). That is, in thine heart, in the inmost recesses of it; where the words or doctrines of the wise should be received in the love of them, and carefully laid up and retained; which will upon reflection yield much pleasure, like Ezekiel's roll, which was in his belly as honey for sweetness; and which also is very profitable as an antidote against sin, Psalm 119:11;

they shall withal be fitted in thy lips; become them, and be suitable and graceful to them: or, "shall be ordered and disposed in" or "by thy lips" (b); being received into the heart, and digested there, they shall easily and freely go off the tongue, which shall be as the pen of a ready writer; they shall be delivered in a regular manner, with great liberty and facility; by a good digestion of Gospel truths, and a comfortable experience of them, persons become apt to teach others.

(a) "in ventre tuo", V. L. Montanus, Junius & Tremellius, Mercerus, Cocceius, Gejerus, Michaelis, Schultens. (b) "disponantur", Vatablus.
