'House of Israel' in the Bible

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

He answered, and said, "I am not sent, but unto the lost sheep of the house of Israel."

So therefore let all the house of Israel know for a surety, that God hath made the same Jesus whom ye have crucified, Lord and Christ."

Then God turned himself, and gave them up, that they should worship the stars of the sky, as it is written in the book of the prophets, 'O ye of the house of Israel: gave ye to me sacrifices and meat offerings by the space of forty years in the wilderness?

For in rebuking them he saith, "Behold the days will come, saith the Lord, and I will finish upon the house of Israel, and upon the house of Judah, a new testament;

For this is the testament that I will make with the house of Israel: After those days, saith the Lord, I will put my laws in their minds, and in their hearts, I will write them, and I will be their God, and they shall be my people.
