Matthew 23:18

18 You say, ‘If people swear by the altar, it's nothing. But if they swear by the gift on the altar, they are obligated to do what they swore.'

Matthew 23:18 Meaning and Commentary

Matthew 23:18

And whosoever shall swear by the altar, it is nothing
These are again the words or savings of the scribes and Pharisees, and express their sentiments and practice: it was usual with them to swear by the altar; and this was reckoned either no sin at all, or such an oath was not accounted binding on a man; he might break, or keep it as he thought fit: of this kind of swearing, we have the following instances. One said to another ^F18,

``swear to me that thou wilt not discover me, and he swore to him; by what did he swear? says R. Jose bar Chanina, (ymynph xbzmb) , "by the innermost altar".''

Again, it is said of Zedekiah ^F19,

``that he (Nebuchadnezzar) made him to swear; by what did he make him to swear? says R. Jose, by the covenant he made him to swear; Rabbi says (xbzmb) , "by the altar" he made him to swear.''

And elsewhere ^F20 it is said of him,

``"and he also rebelled against king Nebuchadnezzar, who made him swear by God", ( 2 Chronicles 36:13 ) . By what did he make him swear? says R. Jose bar Chanina, "by the horns of the innermost altar" he made him swear.''

But whosoever sweareth by the gift that is upon it, he is guilty:
of perjury, if he does not make good his oath; he is bound to perform it, it is obligatory; whatever he swore should be a gift for the altar, he was indispensably obliged to bring it; for whatever he swore by "Korban", or the gift, could never be put to any other use.

Matthew 23:18 In-Context

16 “How terrible it will be for you blind guides who say, ‘If people swear by the temple, it's nothing. But if people swear by the gold in the temple, they are obligated to do what they swore.'

17 You foolish and blind people! Which is greater, the gold or the temple that makes the gold holy?

18 You say, ‘If people swear by the altar, it's nothing. But if they swear by the gift on the altar, they are obligated to do what they swore.'

19 You blind people! Which is greater, the gift or the altar that makes the gift holy?

20 Therefore, those who swear by the altar swear by it and by everything that's on it.
