Matthew 23:18-21

And, ‘Whoever swears by the altar, that is nothing, but whoever swears by the offering on it, he is obligated.’ You blind men, which is more important, the offering, or the altar that sanctifies the offering? Therefore, whoever swears by the altar, swears both by the altar and by everything on it. And whoever swears by the temple, swears both by the temple and by Him who dwells within it.
