Charles Ellicott Commentary Judges 13:6

"Then the woman came and told her husband, saying, A man of God came unto me, and his countenance was like the countenance of the angel of God, very terrible; and I asked him not whence he was, neither told he me his name:" — Judges 13:6 (ASV)

A man of God. —Angels always appeared in human form, and Manoah’s wife, though awe-struck by the majesty of the angel’s appearance, did not know he was other than a prophet. Josephus, writing to please the coarse tastes of Gentile readers, describes the messenger as a tall and beautiful youth, who excited the jealousy of Manoah (Antt. v. 8, § 2).

Very terrible. —Compare to Matthew 28:3-4.

I asked him not whence he was. —The Septuagint omits the negative.
