'Treading' in the Bible

You must not muzzle your ox when it is treading grain.

In those days I saw people in Judah treading winepresses on the Sabbath, bringing in heaps of grain and loading them onto donkeys, along with wine, grapes, figs, and all kinds of loads, and bringing them to Jerusalem on the Sabbath day. So I warned them on the day that they sold these provisions.

I have stirred up one out of the north and he advances, one from the eastern horizon who prays in my name. He steps on rulers as if they were clay, like a potter treading the clay.

For it is written in the law of Moses, "Do not muzzle an ox while it is treading out the grain." God is not concerned here about oxen, is he?

For the scripture says, "Do not muzzle an ox while it is treading out the grain," and, "The worker deserves his pay."
