And it came to pass, that the next day Moses went into the tabernacle of witness; and, behold, the rod of Aaron for the house of Levi was sprouted, and brought forth buds, and bloomed blossoms, and yielded almonds.
All Commentaries on Numbers 17:8 Go To Numbers 17
Ambrose of Milan
AD 397
Paul came to preach the cross of the Lord, an oak that is always verdant. And almonds appear, which are rather hard in shell but more tender in meat—it was right that Aaron’s priestly rod was of the almond tree, and Jeremiah’s staff as well—and double money too. Who would doubt that these gifts were useful? For the life of the patriarch and the preaching of the apostle are always verdant in the heart of each man, and the speech of the saints shines brightly with the splendor of the precepts of salvation, like silver tried by the fire. And it is with reason that they carry double money, for in them there is prefigured the coming of Paul, who presented presbyters who labor in the word and in the teaching with a double honor.
