Deuteronomy 32:37-41

37Then the Lord will ask his people, ‘Why could your gods not help you? Those were the gods that you thought would keep you safe.

38You fed them with the best part of your sacrifices. You let them drink the wine from your offerings. So they should be there to help you! They should keep you safe!

39Realize the truth! I alone am God. There is no other god as well as me. I can kill and I can give life. I can hurt people and I can make them well again. Nobody can stop me doing what I choose to do.

40I lift up my hand to heaven and I make this strong promise: “I promise you this, as surely as I live for ever:

41I will make my sword very sharp. It will move like lightning as I hold it in my hand. I will punish my enemies as they deserve. I will pay back everyone who hates me.
