Numbers 17:8

And it came to pass, that on the morrow Moses went into the tabernacle of witness; and, behold, the rod of Aaron for the house of Levi was budded, and brought forth buds, and bloomed blossoms, and yielded almonds.

Moses went into the tabernacle - being privileged to do so on this occasion by the special command of God; and he there beheld the remarkable spectacle of Aaron's rod-which, according to Josephus, was a stick of an almond tree-bearing fruit in three different stages at once-buds, blossoms, and fruit.
