Numbers 17:8-10

8On the next day Moses went into the tent of the testimony – and the staff of Aaron for the house of Levi had sprouted, and brought forth buds, and produced blossoms, and yielded almonds!

9So Moses brought out all the staffs from before the Lord to all the Israelites. They looked at them, and each man took his staff.

10The Lord said to Moses, “Bring Aaron’s staff back before the testimony to be preserved for a sign to the rebels, so that you may bring their murmurings to an end before me, that they will not die.”
