'Boundaries' in the Bible

Put boundaries for the people all around the mountain and say: Be careful that you don’t go up on the mountain or touch its base. Anyone who touches the mountain will be put to death.

Moses told the LORD, "The people cannot come up to Mount Sinai because you warned us: "Set boundaries around the mountain and consecrate it.'"

I will set your boundaries from the Red Sea to the sea of the Philistines, and from the desert to the River, for I will deliver the inhabitants of the land into your hand, and you will drive them out before you.
