Catena Aurea on Matthew 10:1–4: Rabanus Maurus

This number is typified by many things in the Old Testament; by the twelve sons of Jacob, by the twelve princes of the children of Israel, by the twelve running springs in Helim, by the twelve stones in Aaron’s breastplate, by the twelve loaves of the shew-bread, by the twelve spies sent by Moses, by the twelve stones of which the altar was made, by the twelve stones taken out of Jordan, by the twelve oxen which bare the brazen sea. Also in the New Testament, by the twelve stars in the bride’s crown, by the twelve foundations of Jerusalem which John saw, and her twelve gates.
