'House of Israel' in the Bible

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.
