Jerome, on Matt 23:16

“Woe to you blind guides, that say, Whosoever shall swear by the temple, it is nothing; but he that shall swear by the gold of the temple, is a debtor.”

“As by making broad phylacteries and fringes they sought after the reputation of sanctity, and made this again a means of gain, so now He charges them with being teachers of wickedness by their fraudulent pretence of tradition. For when in any dispute or quarrel, or ambiguous cause, one swore by the temple, and was afterwards convicted of falsehood, he was not held guilty. This is what is meant by that, Whosoever shall swear by the temple, it is nothing, that is, he owes nothing, But if he had sworn by the gold, or by the money which was offered to the Priests in the temple, he was immediately compelled to pay down that by which he had sworn.”
