Jerome
Catena Aurea · Matthäusevangelium 23
Woe unto you, ye blind guides, which say, Whosoever shall swear by the temple, it is nothing; but whosoever shall swear by the gold of the temple, he is a debtor! Ye fools and blind: for whether is greater, the gold, or the temple that sanctifieth the gold? And, Whosoever shall swear by the altar, it is nothing; but whosoever sweareth by the gift that is upon it, he is guilty. Ye fools and blind: for whether is greater, the gift, or the altar that sanctifieth the gift? Whoso therefore shall swear by the altar, sweareth by it, and by all things thereon. And whoso shall swear by the temple, sweareth by it, and by him that dwelleth therein. And he that shall swear by heaven, sweareth by the throne of God, and by him that sitteth thereon.
Again, if one swore by the altar, none held him guilty of perjury; but if he swore by the gift or the victims or the other things which are offered to God upon the altar, this they exacted most rigorously. And all this they did not out of fear of God, but out of covetousness. Thus the Lord charges them with both folly and fraud, inasmuch as the altar is much greater than the victims which are sanctified by the altar.
