Charles H. Spurgeon on Psalms 8:4

Man in Hebrew —infirm or miserable man —by which it is apparent that he speaks of man not according to the state of his creation, but as fallen into a state of sin, and misery, and mortality. Art mindful of him, i.e., carest for him, and conferrest such high favours upon him. The son of man, Hebrew, the son of Adam, that great apostate from and rebel against God; the sinful son of a sinlful father —his son by likeness of disposition and manners, no less than by procreation; all which tends to magnify the divine mercy. That thou visitest, him —not in anger, as that word is sometimes used, but with thy grace and mercy, as it is taken in Genesis 21:1; Exodus 4:31; Psalm 65:9; 106:4; 144:3.
