Ezekiel 37:15-17

The word of the LORD came again unto me, saying, Moreover, thou son of man, take thee one stick, and write upon it, For Judah, and for the children of Israel his companions: then take another stick, and write upon it, For Joseph, the stick of Ephraim, and {for} all the house of Israel his companions: And join them one to another into one stick; and they shall become one in thine hand.
