'Restrain' in the Bible

However, if the ox was in the habit of goring, and its owner has been warned yet does not restrain it, and it kills a man or a woman, the ox must be stoned, and its owner must also be put to death.

But if it was known that the ox had gored previously, and its owner didn't restrain it, he shall certainly repay ox for ox, and the dead ox will become his."
