'House of Israel' in the Bible

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

Let the whole house of Israel therefore know assuredly that God has made him, this Jesus whom ye have crucified, both Lord and Christ.

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

For finding fault, he says to them, Behold, days come, saith the Lord, and I will consummate a new covenant as regards the house of Israel, and as regards the house of Juda;

Because this is the covenant that I will covenant to the house of Israel after those days, saith the Lord: Giving my laws into their mind, I will write them also upon their hearts; and I will be to them for God, and they shall be to me for people.
