New Defender's Study Bible Notes
8:4 What is man. The psalmist exhibits a very modern concept of the infinite magnitude of the heavens in comparison to man.
8:4 the son of man. This is the first reference in the Bible of the phrase “son of man” (or “son of Adam”), a term used some eighty times of Himself by the Lord Jesus.
8:5 lower than the angels. Man is not, as evolutionists think, “a little higher than the apes,” but rather “a little lower than the angels.”
8:6 have dominion. This is a confirmation that God’s original “dominion mandate” (Genesis 1:26-28) is still in effect. This verse is also cited in Hebrews 2:5-8, and there is applied specifically to Christ.
