This is he, that was in the church in the wilderness with the angel which spake to him in the mount Sina, and with our fathers: who received the lively oracles to give unto us: With the angel which spake to him - Stephen shows that Moses received the law by the ministry of angels; and that he was only a mediator between the angel of God and them.
The lively oracles - Λογια ζωντα, The living oracles. The doctrines of life, those doctrines - obedience to which entitled them, by the promise of God, to a long life upon earth, which spoke to them of that spiritual life which every true believer has in union with his God, and promised that eternal life which those who are faithful unto death shall enjoy with him in the realms of glory.
The Greek word λογιον, which we translate oracle, signifies a Divine revelation, a communication from God himself, and is here applied to the Mosaic law; to the Old Testament in general, Romans 3:2; Hebrews 5:12; and to Divine revelation in general, 1 Peter 4:11.
