Numbers 17:1

“Speak to the children of Israel, and take rods from them, one for each fathers’ house, of all their princes according to their fathers’ houses, twelve rods. Write each man’s name on his rod.

You shall write Aaron’s name on Levi’s rod. There shall be one rod for each head of their fathers’ houses.

You shall lay them up in the Tent of Meeting before the covenant, where I meet with you.
