“And whoso shall swear by the temple, sweareth by it, and by him that dwelleth therein.”
King James Version (KJV)
23:20 He that sweareth by the altar, sweareth by it, and by all things thereon - Not only by the gift, but by the holy fire, and the sacrifice; and above all, by that God to whom they belong; inasmuch as every oath by a creature is an implicit appeal to God.
23:23 Judgment - That is, justice: Faith - The word here means fidelity.
Mt 23:21,22 Swear by the temple. Oaths that did they not call binding, Jesus traces to God himself. Compare Mt 5:35. The meaning is that all oaths are by God. There are no distinctions.
