Numbers 17:6-9

6 So 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.

7 Moses placed the staffs before the Lord in the Tent of the Testimony.

8 The next day Moses entered the Tent of the Testimony and saw that Aaron’s staff, which represented the house of Levi, had not only sprouted but had budded, blossomed and produced almonds.

9 Then Moses brought out all the staffs from the Lord’s presence to all the Israelites. They looked at them, and each man took his own staff.
