Isaiah 45:3-5

Young's Literal Translation

³ And have given to thee treasures of darkness, Even treasures of secret places, So that thou knowest that I, Jehovah, Who am calling on thy name -- [am] the God of Israel.

⁴ For the sake of my servant Jacob, And of Israel My chosen, I call also thee by thy name, I surname thee, And thou hast not known Me.

⁵ I [am] Jehovah, and there is none else, Except Me there is no God, I gird thee, and thou hast not known Me.
