Numbers 17:6-10
English Standard Version
Chapter 17
6Moses spoke to the people of Israel. And all their chiefs gave him staffs, one for each chief, according to their fathers ' houses, twelve staffs. And the staff of Aaron was among their staffs. 7And Moses deposited the staffs before the Lord in the tent of the testimony.
8On the next day Moses went into the tent of the testimony, and behold, the staff of Aaron for the house of Levi had sprouted and put forth buds and produced blossoms, and it bore ripe almonds.
9Then Moses brought out all the staffs from before the Lord to all the people of Israel. And they looked, and each man took his staff.
10And the Lord said to Moses, "Put back the staff of Aaron before the testimony, to be kept as a sign for the rebels, that you may make an end of their grumblings against me, lest they die."
