Albert Barnes Commentary Judges 13:2

"And there was a certain man of Zorah, of the family of the Danites, whose name was Manoah; and his wife was barren, and bare not." — Judges 13:2 (ASV)

Zorah - See the marginal reference.

His wife was barren - To mark more distinctly the high providential destiny of the child that was eventually born. Compare the similar circumstances of the birth of Isaac, Jacob, Samuel, and John the Baptist.
