1 Corinthians 9:8-10

Am I expressing merely a human opinion, or does the law say the same thing? For the law of Moses says, “You must not muzzle an ox to keep it from eating as it treads out the grain.” Was God thinking only about oxen when he said this? Wasn’t he actually speaking to us? Yes, it was written for us, so that the one who plows and the one who threshes the grain might both expect a share of the harvest.
