Deuteronomy 25:4

As the Gentiles used to do, having divers devices to keep them from eating when they trod out the corn, which they did in those parts and times by oxen, Hosea 10:11, either immediately by their hoofs, Isaiah 28:28 Micah 4:13, or by drawing carts or other instruments over the corn, Isaiah 25:10, Isaiah 28:27 41:15 Amos 1:3. Hereby God taught them humanity and kindness, even to their beasts that served them, Proverbs 12:10, and much more to their servants or other men who laboured for them, and especially to their ministers, 1 Corinthians 9:9.
