Judges 11:2

2. They thrust out Jephthah Their father, Gilead, was a man of wealth and power, and they were unwilling that the son of a strange woman and a harlot should share with them the paternal inheritance. Compare Genesis 21:10; Genesis 25:6. The law placed a bastard on the same footing with an Ammonite or a Moabite. Deuteronomy 23:2-3. Neither could enter the congregation of the Lord until the tenth generation. Mark that he who by the law was placed in the same category with the Ammonites was called to be the conqueror of those incestuous sons of Lot.

Strange woman Hebrew, another woman. “Other is here to be taken in a bad sense, as in the expression other gods. As those are spurious gods, so another woman is a spurious wife.” Cassel.
