Isaiah 45:4 WEB

²  I will go before you, and make the rough places smooth; I will break in pieces the doors of brass, and cut in sunder the bars of iron;

³  and I will give you the treasures of darkness, and hidden riches of secret places, that you may know that it is I, Yahweh, who call you by your name, even the God of Israel.

⁴  For Jacob my servant's sake, and Israel my chosen, I have called you by your name: I have surnamed you, though you have not known me.

⁵  I am Yahweh, and there is none else; besides me there is no God. I will gird you, though you have not known me;

⁶  that they may know from the rising of the sun, and from the west, that there is none besides me: I am Yahweh, and there is no one else.
