What does Exodus 21:29 mean?

But if the ox was wont to gore in time past, and it hath been testified to its owner, and he hath not kept it in, but it hath killed a man or a woman; the ox shall be stoned, and its owner also shall be put to death.

But if the ox were wont to push with his horn in time past, and it hath been testified to his owner, and he hath not kept him in, but that he hath killed a man or a woman; the ox shall be stoned, and his owner also shall be put to death.

But if the ox was wont to gore in time past, and it hath been testified to its owner, and he hath not kept it in, but it hath killed a man or a woman; the ox shall be stoned, and its owner also shall be put to death.

But if the ox has frequently done such damage in the past, and the owner has had word of it and has not kept it under control, so that it has been the cause of the death of a man or woman, not only is the ox to be stoned, but its owner is to be put to death.

and if the ox is <FI>one<Fi> accustomed to gore heretofore, and it hath been testified to its owner, and he doth not watch it, and it hath put to death a man or woman, the ox is stoned, and its owner also is put to death.

But if the ox was wont to push with his horn yesterday, and the day before, and they warned his master, and he did not shut him up, and he shall kill a man or a woman: then the ox shall be stoned, and his owner also shall be put to death.

But if the ox have gored heretofore, and it have been testified to its owner, and he have not kept it in, and it kill a man or a woman, — the ox shall be stoned, and its owner also shall be put to death.
