Numbers 17:4-8

4Place them in the tent of meeting in front of the ark of the covenant law, where I meet with you. 5The staff belonging to the man I choose will sprout, and I will rid myself of this constant grumbling against you by the Israelites.” 6So Moses spoke to the Israelites, and their leaders gave him twelve staffs, one for the leader of each of their ancestral tribes, and Aaron’s staff was among them. 7Moses placed the staffs before the Lord in the tent of the covenant law. 8The next day Moses entered the tent and saw that Aaron’s staff, which represented the tribe of Levi, had not only sprouted but had budded, blossomed and produced almonds.
