'King of Israel' in the Bible

Now it came to pass in the days of Ahaz the son of Jotham, the son of Uzziah, king of Judah, that Rezin king of Aram (Syria) and Pekah the son of Remaliah, king of Israel, went up to Jerusalem to wage war against it, but they could not conquer it.

“Because these people (Judah) have refused the gently flowing waters of ShiloahAnd rejoice in Rezin [the king of Aram] and Remaliah’s son [Pekah the king of Israel],

“For the Lord, the King of Israel and his Redeemer, the Lord of hosts says this,‘I am the First and I am the Last;And there is no God besides Me.
