1 Corinthians 9:9-10

9For it is written in the Law of Moses: “Do not muzzle an ox while it is treading out the grain.” Deut. 25:4 Is it about oxen that God is concerned? 10Surely he says this for us, doesn’t he? Yes, this was written for us, because whoever plows and threshes should be able to do so in the hope of sharing in the harvest.
