'House of Israel' in the Bible

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

He answered, “I was commissioned by God and sent only to the lost sheep of the house of Israel.”

Therefore let all the house of Israel recognize beyond all doubt that God has made Him both Lord and Christ (Messiah, Anointed)—this Jesus whom you crucified.”

let it be known and clearly understood by all of you, and by all the people of Israel, that in the name of Jesus Christ the Nazarene, whom you [demanded be] crucified [by the Romans and], whom God raised from the dead—in this name [that is, by the authority and power of Jesus] this man stands here before you in good health.

But God turned away [from them] and handed them over to serve the host of heaven. As it is written and forever remains written in the book of the prophets, ‘It was not [really] to Me that you offered victims and sacrifices for forty years in the wilderness, was it, O house of Israel?

However, God finds fault with them [showing its inadequacy] when He says,“Behold, the days will come, says the Lord,When I will make and ratify a new covenantWith the house of Israel and with the house of Judah;

“For this is the covenant that I will make with the house of IsraelAfter those days, says the Lord:I will imprint My laws upon their minds [even upon their innermost thoughts and understanding],And engrave them upon their hearts [effecting their regeneration].And I will be their God,And they shall be My people.
