'Offspring' in the Bible

And these were the people who went up from Tel-melah, Tel-harsha, Cherub, Addan, and Immer. But having no knowledge of their fathers' families or offspring, it was not certain that they were Israelites;

For they have taken some of their daughters as wives for themselves and for their sons, so that the holy race has intermingled with the peoples of the lands. Indeed, the officials and chief men have been foremost in this unfaithful act and direct violation [of God’s will].”

Therefore let us enact a covenant with our God to send away all these women and their offspring, in keeping with your counsel, my lord, and that of those who respect the commandments of our God. And let it be done according to the law.

All these had taken strange wives; and some of them had wives by whom they had offspring.
