Psalms 119:16

I will delight myself in thy statutes,.... In looking over them; in meditating on them; in obeying them, and walking according to them; as every good man does delight in the law of the Lord, after the inward man, Romans 7:22; see Psalms 119:24;

I will not forget thy word: he took all proper methods to fix it in his memory; he laid it up in his mind; he meditated upon it in his heart, and he talked of it with his lips, Psalms 119:11.
