Is There A God Besides Me?

Isaiah 44:6-8

6  Thus says the LORD the King of Israel, and his redeemer the LORD of hosts; I am the first, and I am the last; and beside me there is no God.
7  And who, as I, shall call, and shall declare it, and set it in order for me, since I appointed the ancient people? and the things that are coming, and shall come, let them shew unto them.
8  Fear you not, neither be afraid: have not I told you from that time, and have declared it? you are even my witnesses. Is there a God beside me? yes, there is no God; I know not any.
