Exodus 19:23

And Moses said to God, The people will not be able to approach to the mount of Sina, for thou hast solemnly charged us, saying, Set bounds to the mountain and sanctify it.

And Moses said unto the Lord, The people cannot come up to mount Sinai: for thou chargedst us, saying, Set bounds about the mount, and sanctify it.

Moses said to Yahweh, “The people can’t come up to Mount Sinai, for you warned us, saying, ‘Set bounds around the mountain, and sanctify it.’”
