Thus saith 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. 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. Fear ye not, neither be afraid: have not I told thee from that time, and have declared it? ye are even my witnesses. Is there a God beside me? yea, there is no God; I know not any.
The LORD, the King of Israel, is unique, as He is the only true God. He challenges any so-called god to predict the future as He does, especially with regard to the ancient people, Israel. His people need not fear any challenge to His supremacy. They are His witnesses that He has foretold the future, and that He is the only God. He Himself does not know of any other genuine God and challenges Israel to find one that is as powerful as He.
