The angel of Yahweh said to Manoah, Though you detain me, I won't eat of your bread; and if you will make ready a burnt offering, you must offer it to Yahweh. For Manoah didn't know that he was the angel of Yahweh.
"Manoah was the first to speak but the last to recover his composure, reflecting the widely-held belief that if a man saw God he would die (Exodus 33:20; Judges 6:22-23)." [Note: Cundall and Morris, p. 160.]
