'House of Israel' in the Bible

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

For this is the covenant that I will make with the house of Israel after those days, saith the Lord: I will put my laws into their mind, and on their hearts will I write them; and I will be to them a God, and they shall be to me a people.
