Hosea 1:10-11

10 aYet the number of the sons of Israel Will be like the 1sand of the sea, Which cannot be measured or numbered; And 2in the place Where it is said to them, "You are 3not My people," It will be said to them, "You are the 4sons of the living God."
11 And the 5sons of Judah and the sons of Israel will be 6gathered together, And they will appoint for themselves 7one leader, And they will go up from the land, For great will be the day of Jezreel.
