'House of Israel' in the Bible

but go rather to the sheep that are lost of the house of Israel.

But he said in reply, I am not sent, save only to the lost sheep of the house of Israel.

Let all the house of Israel therefore know assuredly, that God hath made him Lord and Messiah, even that very Jesus whom ye crucified.

Then God turned, and gave them up to worship the host of heaven; as it is written in the book of the prophets, Have ye offered me slain beasts and sacrifices forty years in the wilderness, O house of Israel?

For finding fault with them, he saith, "Behold, the days are coming, saith the Lord; and I will accomplish for the house of Israel and for the house of Judah a new covenant:

For this is the covenant which I will make with the house of Israel after those days, saith the Lord; giving my laws to their understanding, even on their hearts will I inscribe them: and I will be to them a God, and they shall be to me a people.
