Matthew Henry Commentary Psalms 32:8-11

"I will instruct thee and teach thee in the way which thou shalt go: I will counsel thee with mine eye upon thee. Be ye not as the horse, or as the mule, which have no understanding; Whose trappings must be bit and bridle to hold them in, [Else] they will not come near unto thee. Many sorrows shall be to the wicked; But he that trusteth in Jehovah, lovingkindness shall compass him about. Be glad in Jehovah, and rejoice, ye righteous; And shout for joy, all ye that are upright in heart." — Psalms 32:8-11 (ASV)

God teaches by His word and guides with the secret intimations of His will. David gives a word of caution to sinners. The reason for this caution is that the way of sin will certainly end in sorrow. Here is a word of comfort to saints. They may see that a life of communion with God is by far the most pleasant and comfortable. Let us rejoice, O Lord Jesus, in You and in Your salvation; then we will truly rejoice.
