5 For the name of Divinity is given for the highest honour in the world, and with whomsoever God is well pleased, He applies it to him. But however, the names of God are many and are venerable, as He delivered His names to Moses, saying to him:— I am the God of your fathers, the God of Abraham and the God of Isaac and the God of Jacob. This is My Name for ever, and this is My memorial unto generations. And He called His name Ahiyah ashar Ahiyah, El Shaddai and Adonai Sabaoth. By these names is God called. The great and honourable name of Godhead He withheld not from His righteous ones; even as, though He is the great King, without grudging He applied the great and honourable name of Kingship to men who are His creatures.
