'Restrain' in the Bible

But if it was a goring ox {before} and its owner was warned and did not restrain it and it kills a man or a woman, the ox will be stoned, and the owner also will be put to death.

Or if it was known that it was a goring ox {before} and its owner did not restrain it, he will surely make restitution, an ox in place of the ox, and the dead [one] will be for him.
