‘What is His Name? – What shall I say to them?” Hashem answered Moses, “I Shall Be As I Shall Be.” And He said, “So shall you say to the Children of Israel. ‘I Shall Be has sent me to you.” So said further to Moses, “So shall you say to the Children of Israel, ‘Hashem, the God of your forefathers, the God of Abraham, the God of Isaac, and the God of Jacob, has dispatched me to you. This is My Name forever, and this is My remembrance from generation to generation.’

You shall not take the Name of Hashem, your God, in vain, for Hashem will not absolve anyone who takes His Name in vain.

Be careful regarding everything I have said to you. The name of the gods of others you shall not mention, nor shall your mouth cause it to be heard.

Proclaim and approach; even let [your leaders] take counsel together: Who let this be heard from aforetimes, or related it from of old? Is it not I, Hashem? There is no other god besides Me; there is no righteous god besides Me and no savior other than Me.
Turn to Me and be saved, all ends of the earth, for I am God and there is no other.
I swear by Myself, righteousness has gone forth from My mouth, a word that will not be rescinded: that to Me shall every knee kneel and every tongue swear.
