'Ox' in the Bible

Then the Lord answered him, "You hypocrites! Does not each of you on the Sabbath untie his ox or his donkey from its stall, and lead it to water?

Then he said to them, "Which of you, if you have a son or an ox that has fallen into a well on a Sabbath day, will not immediately pull him out?"

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."

The first living creature was like a lion, the second creature like an ox, the third creature had a face like a man's, and the fourth creature looked like an eagle flying.
