Parallel
Exodus 19:23
Brenton's English Septuagint · Berean Standard Bible
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.
But Moses said to the LORD, “The people cannot come up Mount Sinai, for You solemnly warned us, ‘Put a boundary around the mountain and set it apart as holy.’”
