Isaiah 45:4

For Jacob my servant's sake, and Israel mine elect, I have even called thee by thy name: I have surnamed thee, though thou hast not known me.

For Jacob, my servant's sake, and Israel mine elect, I have even called thee by thy name - (note, ; Isaiah 43:14.)

I have surnamed thee - i:e., designated thee to carry out my design of restoring Judah (see note, ; ; ). Maurer here, as in , translates, akanneka, 'I have addressed thee by an honourable name.'

Though thou hast not known me - previous to my calling thee to this office; after God's call Cyrus did know Him in some degree (Ezra 1:1).
