Ezekiel 37:18-19

18“When your people ask you, ‘Won’t you tell us what you mean by this?’

19say to them, ‘This is what the Sovereign Lord says: I am going to take the stick of Joseph—which is in Ephraim’s hand—and of the Israelite tribes associated with him, and join it to Judah’s stick. I will make them into a single stick of wood, and they will become one in my hand.’
