Matthew 23:17

“But woe to you, scribes and Pharisees, hypocrites! Because you shut up the Kingdom of Heaven against men; for you don’t enter in yourselves, neither do you allow those who are entering in to enter.

Woe to you, scribes and Pharisees, hypocrites! For you travel around by sea and land to make one proselyte; and when he becomes one, you make him twice as much a son of Gehenna as yourselves.

“Woe to you, you blind guides, who say, ‘Whoever swears by the temple, it is nothing; but whoever swears by the gold of the temple, he is obligated.’

And, ‘Whoever swears by the altar, it is nothing; but whoever swears by the gift that is on it, he is obligated.’

You blind fools! For which is greater, the gift, or the altar that sanctifies the gift?

He therefore who swears by the altar, swears by it and by everything on it.
