Numbers 17:5-8

17:5 And the staff of the man whom I choose will blossom; so I will rid myself of the complaints of the Israelites, which they murmur against you.”

17:6 So Moses spoke to the Israelites, and each of their leaders gave him a staff, one for each leader, according to their tribes – twelve staffs; the staff of Aaron was among their staffs. 17:7 Then Moses placed the staffs before the Lord in the tent of the testimony.

17:8 On 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!
