Exodus 19:16–25

²⁰The Lord came down on Mount Sinai at the top of the mountain. Then the Lord summoned Moses to the top of the mountain, and he went up. ²¹The Lord directed Moses, “Go down and warn the people not to break through to see the Lord; otherwise many of them will die. ^u22Even the priests who come near the Lord must purify themselves or the Lord will break out in anger against them.” ^v

²³But Moses responded to the Lord, “The people cannot come up Mount Sinai, since You warned us: Put a boundary around the mountain and consider it holy.” ²⁴And the Lord replied to him, “Go down and come back with Aaron. But the priests and the people must not break through to come up to the Lord, or He will break out in anger against them.” ²⁵So Moses went down to the people and told them.
