'Limits' in the Bible

And you must set limits [for] the people all around, saying, 'Guard yourselves {against} going up to the mountain and touching its edge. Anyone touching the mountain will certainly be put to death.

And Moses said to Yahweh, "The people are not able to go up to Mount Sinai, because you yourself warned us, saying, 'Set limits [around] the mountain and consecrate it.'"
