TSK · Exodus 20:19

So Jacob named the place Peniel, explaining,“Certainly I have seen God face to face and have survived.”

(I was standing between the LORD and you at that time to reveal the LORD’s message to you, because you were afraid of the fire and would not go up the mountain.) He said:

This accords with what happened at Horeb in the day of the assembly. You asked the LORD your God:“Please do not make us hear the voice of the LORD our God any more or see this great fire any more lest we die.”

Why then was the law given? It was added because of transgressions, until the arrival of the descendant to whom the promise had been made. It was administered through angels by an intermediary.
