Isaiah 45:2-3
Isaiah 45:2-3 ASV
I will go before thee, and make the rough places smooth; I will break in pieces the doors of brass, and cut in sunder the bars of iron; and I will give thee the treasures of darkness, and hidden riches of secret places, that thou mayest know that it is I, Jehovah, who call thee by thy name, even the God of Israel.
