'House of Israel' in the Bible

But go ye rather to the lost sheep of the house of Israel.

And He responding said, I am not sent except to the lost sheep of the house of Israel.

Then let all the house of Israel assuredly know that God hath made this same Jesus, whom you crucified, both Lord and Christ.

And God turned away, and gave them up to serve the host of the heaven; as has been written in the book of the prophets: Slain victims and sacrifices you have not brought unto me forty years in the wilderness, O house of Israel.

For finding fault with them, he says, Behold the days are coming, says the Lord, and I will perfect upon the house of Israel and upon the house of Judah, a new covenant:

Because this is my covenant which I will establish with the house of Israel after these days, says the Lord; having given my laws in their mind, I will also write them on their heart; and I will be to them a God, and they shall be unto me a people.
