# You must not put a muzzle on an ox while it threshes the grain

Paul is using this quotation as a metaphor meaning that church leaders deserve to receive payment from the Christian community for their work. (See: [[rc://en/ta/man/jit/figs-metaphor]])

# muzzle

place a sleeve over an animal's snout and mouth to prevent it from eating (See: [[rc://en/ta/man/jit/translate-unknown]])

# threshes the grain

An ox "threshes the grain" when it walks on or pulls a heavy object over the cut grain to separate the grain from the stalks. The ox was allowed to eat some of the grain as it worked.
