Romans 9:25-29

25As he says in Hosea: “I will call them ‘my people’ who are not my people; and I will call her ‘my loved one’ who is not my loved one,” Hosea 2:23

26and, “In the very place where it was said to them, ‘You are not my people,’ there they will be called ‘children of the living God.’ ” Hosea 1:10

27Isaiah cries out concerning Israel: “Though the number of the Israelites be like the sand by the sea, only the remnant will be saved.

28For the Lord will carry out his sentence on earth with speed and finality.” Isaiah 10:22,23 (see Septuagint)

29It is just as Isaiah said previously: “Unless the Lord Almighty had left us descendants, we would have become like Sodom, we would have been like Gomorrah.” Isaiah 1:9
