Which is greater, the gift or the altar that makes the gift holy?

Jesus uses this question to rebuke the Pharisees for treating the gift as if it were more important than the altar. Alternate translation: "The altar that makes the gift holy is greater than the gift!" (See: rc://en/ta/man/jit/figs-rquestion)

"the altar that makes the gift special to God"
