What does Judges 13:17 mean?

Manoah is grateful to a stranger, a "man of God" whom he thinks is some kind of prophet (Judges 13:2–14). That figure brought good news that Manoah and his wife will finally have a child, a son. The couple wants to honor this visitor in some way, not understanding this is "the angel of the LORD;" in this context, this means they are speaking with some temporary manifestation of God, Himself. After Manoah offers a special meal, the "man" suggested using the goat and other food as burnt offering, instead. Manoah will do this, but first he has a question.

Once again expressing trusting faith that God's promises will come true, Manoah asks for the "man's" name. He wants to know who to honor when these prophecies are fulfilled. This faith in the truthfulness of a stranger's God-given message is impressive. That makes it more curious that Manoah seems slow to recognize the stranger as anything more than merely human. As the following verses show, it will take more hints and surprises to make the situation clear.
