1 Corinthians 9:8-10 New Revised Standard Version, Anglicised Catholic Edition (NRSVACE)
8 Do I say this on human authority? Does not the law also say the same? 9 For it is written in the law of Moses, ‘You shall not muzzle an ox while it is treading out the grain.’ Is it for oxen that God is concerned? 10 Or does he not speak entirely for our sake? It was indeed written for our sake, for whoever ploughs should plough in hope and whoever threshes should thresh in hope of a share in the crop.
