Numbers 17:1 KJV

1And the LORD spake unto Moses, saying,

2Speak unto 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.
