'Ox' in the Bible

Therefore the Lord answered him, "You hypocrites! Doesn't each one of you free his ox or his donkey from the stall on the Sabbath, and lead him away to water?

He answered them, "Which of you, if your son or an ox fell into a well, wouldn't immediately pull him out on a Sabbath day?"

For it is written in the law of Moses, "You shall not muzzle an ox while it treads out the grain." Is it for the oxen that God cares,

For the Scripture says, "You shall not muzzle the ox when it treads out the grain." And, "The laborer is worthy of his wages."
