Summary: God calls and empowers Cyrus for the sake of Israel, showing that He alone is God and there is no other.
Thus says the LORD to his anointed, Cyrus, whose right hand I grasp, subduing nations before him, and making kings run in his service, opening doors before him and leaving the gates unbarred:
For the sake of Jacob, my servant, of Israel, my chosen one, I have called you by your name, giving you a title, though you knew me not.
I am the LORD and there is no other, there is no God besides me.
It is I who arm you, though you know me not, so that toward the rising and the setting of the sun people may know that there is none besides me.
I am the LORD, there is no other.
