8:3 thou hast ordained. God has “ordained” all the heavenly bodies and their motions; these were not established by an imaginary primeval “big bang.”

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.
