'Offspring' in the Bible

Behold, I am going to rebuke your offspring, and I will spread refuse on your faces, the refuse of your feasts; and you will be taken away with it.

But not one has done so who has a remnant of the Spirit. And what did that one do while he was seeking a godly offspring? Take heed then to your spirit, and let no one deal treacherously against the wife of your youth.
