"Moses wanted to know God's name, and God tells him, 'I am that I am'; that is to say, 'I am called--or to be called-in accordance with my work in this world.' When I judge mankind I am אלהים Elohim, that being the title or designation for judgment. When I war with the wicked I am known as צבאות Zevooth. When I execute judgment for the sins of man I am known as אלשדי El Shadai, and when I am visiting the world with mercy I am אבני or יהוה Adonoi, the Eternal."
