Sur in the Bible

And a third part shall be at the gate of Sur; and a third part at the gate behind the guard: so shall ye keep the watch of the house, that it be not broken down.

And king Ahaz will go up to the meeting of Tiglath-Pileser king of As-sur to Damascus, and he will see an altar which was in Damascus: and king Ahaz will send to Urijah the priest a likeness of the altar and its structure, for all its work.
