'House of Israel' in the Bible

but go rather to the lost sheep of the house of Israel;

But he answered and said, I am not sent, except to the lost sheep of the house of Israel.

Let all the house of Israel therefore know certainly, that God has made this Jesus whom you crucified both Lord and Christ.

And God turned and gave them up to serve the host of heaven, as it is written in the book of the prophets; Did you offer victims and sacrifices to me forty years in the wilderness, house of Israel,

For finding fault with them he says, Behold, the days come, says the Lord, that I will make with the house of Israel and the house of Judah, a new covenant,

This is the covenant that I will make with the house of Israel after those days, says the Lord; I will put my laws in their minds, and will write them in their hearts, and I will be to them a God, and they shall be to me a people.
