Ezekiel 37:15-17

And the word of the Lord came to me, saying, And you, son of man, take one stick, writing on it, For Judah and for the children of Israel who are in his company: then take another stick, writing on it, For Joseph, the stick of Ephraim, and all the children of Israel who are in his company: Then, joining them one to another, make them one stick, so that they may be one in your hand.
