Isaiah 45:5
The monotheistic assertion—'I am Yahweh, and there is no other; besides me there is no god. I arm you, though you do not know me'—reiterates absolute monotheism while affirming that God empowers Cyrus. The statement that Cyrus does not know God contrasts with God's complete knowledge and control of Cyrus. The emphasis that God provides military power ('I arm you') suggests that conquest flows from divine enablement. This verse prevents Cyrus from supposing that his success derives from his own power or from other gods.
