'House of Israel' in the Bible

So God turned away from them and gave them over to worship the heavenly bodies. As it is written in the book of the Prophets: "O house of Israel, you didn't offer me slaughtered animals and sacrifices those 40 years in the wilderness, did you?

but God found something wrong with his people when he said, "Look! The days are coming, declares the Lord, when I will establish a new covenant with the house of Israel and with the house of Judah.

For this is the covenant that I will make with the house of Israel after that time, declares the Lord: I will put my laws in their minds and write them on their hearts. I will be their God, and they will be my people.
