Numbers 17:1-4

Then the Lord spoke to Moses, saying,

“Speak to the sons of Israel, and obtain from them a staff for each father’s household: twelve staffs, from all their leaders for their fathers’ households. You shall write each man’s name on his staff,

and write Aaron’s name on the staff of Levi; for there is to be one staff for the head of each of their fathers’ households.

You shall then leave them in the tent of meeting in front of the testimony, where I meet with you.
