'Warned' in the Bible

Moses said to the Lord, "The people are not able to come up to Mount Sinai, because you solemnly warned us, 'Set boundaries for the mountain and set it apart.'"

But if the ox had the habit of goring, and its owner was warned, and he did not take the necessary precautions, and then it killed a man or a woman, the ox must be stoned and the man must be put to death.
