Numbers 17:5-8

5And it shall come to pass, that the rod of the man whom I shall choose shall bud: and I will make to cease from me the murmurings of the children of Israel, which they murmur against you. 6And Moses spake unto the children of Israel; and all their princes gave him rods, for each prince one, according to their fathers’ houses, even twelve rods: and the rod of Aaron was among their rods. 7And Moses laid up the rods before Jehovah in the tent of the testimony.

8And it came to pass on the morrow, that Moses went into the tent of the testimony; and, behold, the rod of Aaron for the house of Levi was budded, and put forth buds, and produced blossoms, and bare ripe almonds.
