Parallel
Exodus 19:12
Brenton's English Septuagint · Berean Standard Bible
And thou shalt separate the people round about, saying, Take heed to yourselves that ye go not up into the mountain, nor touch any part of it: every one that touches the mountain shall surely die.
And you are to set up a boundary for the people around the mountain and tell them, ‘Be careful not to go up on the mountain or touch its base. Whoever touches the mountain shall surely be put to death.
