Numbers 17:1-4

1And the LORD spoke to Moses, saying,

2Speak to the children of Israel, and take of every one of them a rod according to the house of their fathers, of all their princes according to the house of their fathers twelve rods: write thou every man’s name upon his rod.

3And thou shalt write Aaron’s name upon the rod of Levi: for one rod shall be for the head of the house of their fathers.

4And thou shalt lay them in the tabernacle of the congregation before the testimony, where I will meet with you.
