'House of Israel' in the Bible

but go to the lost sheep of the house of Israel.

But he answered and said, I am sent only to the lost sheep of the house of Israel.

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

Then God turned away, and gave them up to worship the host of heaven, as it is written in the book of the prophets, "O house of Israel, did ye offer to me your victims and sacrifices, for the space of forty years in the wilderness?

as we see there was, for after complaining of them, He adds, "Behold the days come, saith the Lord, that I will make a new covenant with the house of Israel, and with the house of Judah:

But 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 I will inscribe them on their hearts; and I will be to them a God, and they shall be to me a people.
