Adam Clarke's Commentary on the Bible

Verse 8 (Psalms 32:8)

I will instruct thee - These are probably the Lord's words to David. Seeing thou art now sensible of the mercy thou hast received from me, and art purposing to live to my glory, I will give thee all the assistance requisite. I will become thy Instructor, "and will teach thee," in all occurrences, "the way thou shouldst go." I will keep mine eyes upon thee, and thou shalt keep thine upon me: as I go, thou must follow me; and I will continually watch for thy good.
