Hab 3:4 His brightness was like the light; rays flashed from his hand; and there he veiled his power.
Between the writing of the first and second sets of tablets of the Ten Commandments, Moses pled with God to see Him literally face to face. God passed by Moses, but shielded him (veiled His power) from seeing His face. (Ex 33:12-23). The first thing God is quoted as speaking into existence is light (Gen 1:3). David (Ps 27:1), Isaiah (Is 10:17), and various other Old Testament writers said that God is light. In the New Testament Jesus is called a light and even proclaims himself to be the light of the world (Jn 8:12). At the conclusion of John’s Revelation we learn that God Almighty and Jesus are the light source in heaven (Rev 21:23-24, 22:5).
