'Muzzle' in the Bible

"You shall not muzzle an ox {when he is threshing}.

I said, "I will guard my ways {that I may not sin} with my tongue. I will keep a muzzle over my mouth as long as [the] wicked [are] before me."

For in the law of Moses it is written, "You must not muzzle an ox [while it] is threshing." It is not about oxen God is concerned, is it?

For the scripture says, "You must not muzzle an ox [while it] is threshing," and "The worker [is] worthy of his wages."
