Psalms 32:8

8. I will instruct thee The current of modern criticism supposes David to be here speaking. The psalm is a “maschil,” (see on title.) He rebukes those of “no understanding,” (Psalms 32:9,) and this instructive discourse is what he promised after restoration. Psalms 51:13. It is the dictate as well as duty of a renewed heart to teach others the way. See Psalms 34:11; Luke 22:32.

Guide thee with mine eye The marginal reading is better: “I will counsel thee, mine eye shall be upon thee,” meaning, while I undertake the office of tutor and guide, I will exercise toward you the most watchful, accurate, and personal care. But it is often understood of God as speaking, and certainly this gives a very comforting sense.
