Exodus 19:13

19:13 No hand will touch him25—but he will surely be stoned or shot through, whether a beast or a human being;26 he must not live.’ When the ram’s horn sounds a long blast they may27 go up on the mountain.”

25	sn There is some ambiguity here. The clause either means that no man will touch the mountain, so that if there is someone who is to be put to death he must be stoned or shot since they could not go into the mountain region to get him, or, it may mean no one is to touch the culprit who went in to the region of the mountain.
26	tn Heb “a man.”
27	tn The nuance here is permissive imperfect, “they may go up.” The ram’s horn would sound the blast to announce that the revelation period was over and it was permitted then to ascend the mountain.
