Wife of Manoah
The wife of Manoah is an unnamed character in the Book of Judges in the Hebrew Bible. She is introduced in Judges 13:2 as barren woman. The Angel of the Lord appears to her and tells her she will have a son. This does in fact, happen, and she gives birth to Samson.
J. Cheryl Exum argues that the wife of Manoah is more perceptive than her husband, in that she "senses at once something otherworldly" about the man of God who visits her, and "recognizes a divine purpose behind the revelation."
Ancient Rabbinic tradition identifies this woman as the Hazelelponi mentioned in 1 Chronicles 4:3.
