'King of Israel' in the Bible

And it happened in the days of Ahaz the son of Jotham, the son of Uzziah, king of Judah, Rezin the king of Syria, and Pekah the son of Remaliah, king of Israel, went up toward Jerusalem to war against it, but could not overcome it.

So says Jehovah, the King of Israel, and His redeemer Jehovah of Hosts; I am the first, and I am the last; and besides Me there is no God.
