Matthew Henry on Judges 13:15-23
We have here an account,
I. Of what further passed between Manoah and the angel at this interview. It was in kindness to him that while the angel was with him it was concealed from him that he was an angel; for, had he known it, it would have been such a terror to him that he durst not have conversed with him as he did (Jdg 13:16): He knew not that he was an angel. So Christ was in the world, and the world knew him not. Verily thou art a God that hidest thyself. We could not bear the sight of the divine glory unveiled.

Keil & Delitzsch on Judges 13:21-23
From that time forward the Lord did not appear to them again. But Manoah was afraid that he and his wife should die, because they had seen God (on this belief, see the remarks on Gen 16:13 and Exo 33:20). His wife quieted his fears, however, and said, "Jehovah cannot intend to kill us, as He has accepted our sacrifice, and has shown us all this" (the twofold miracle). "And at this time He has not let us see such things as these." כּעת, at the time in which we live, even if such things may possibly have taken place in the hoary antiquity.
