Numbers 17:8-10

8The next day, Moses entered the Tent of Testimony and behold, Aaron’s staff, from the house of Levi, had sprouted, blossomed, and produced almonds!

9Moses then brought all the staffs from Adonai’s Presence to all Bnei-Yisrael. They looked and each man took his staff.

10Adonai said to Moses, “Put Aaron’s staff back in front of the Testimony to keep as a sign to the sons of rebellion, so that it may put an end to their grumblings against Me, and so they will not die.”
