Matthew 23:20

20 When you swear ‘by the altar,’ you are swearing by it and by everything on it.

Matthew 23:20 Meaning and Commentary

Matthew 23:20

Whosoever therefore shall swear by the altar,
&c.] Not that Christ allowed of swearing by the altar, or by the temple, or by heaven, or by any creature, animate or inanimate; for such swearing is elsewhere disapproved of by him, and forbid, but if a man did swear by the altar, he ought to know, and consider that he not only

sweareth by it,
but by all the gifts, and offerings that are brought, and laid upon it,

and by all things thereon;
whatever gifts and sacrifices are offered upon it; which, by being put there, become holy, as the altar itself: so that he that swears by the altar, swears also by the gifts of the altar; and consequently, according to their own traditions, such oaths must be binding.

Matthew 23:20 In-Context

18 And you say that to swear ‘by the altar’ is not binding, but to swear ‘by the gifts on the altar’ is binding.

19 How blind! For which is more important—the gift on the altar or the altar that makes the gift sacred?

20 When you swear ‘by the altar,’ you are swearing by it and by everything on it.

21 And when you swear ‘by the Temple,’ you are swearing by it and by God, who lives in it.

22 And when you swear ‘by heaven,’ you are swearing by the throne of God and by God, who sits on the throne.
