'House of Israel' in the Bible

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

But he answering said, I am not sent but to the lost sheep of the house of Israel.

Therefore let all the house of Israel know assuredly, That God hath made this Jesus whom ye crucified, both Lord and Christ.

And God turned and gave them up, to worship the host of heaven; as it is written in the book of the prophets, Have ye offered victims and sacrifices to me, for forty years in the wilderness, O house of Israel?

For finding fault with them he saith, Behold the days come, saith the Lord, when I will finish a new covenant with the house of Israel and with the house of Judah:

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