'Children' in the Bible

So now do not give your daughters to their sons or take their daughters for your sons; and never seek their peace or their prosperity, so that you may be strong and eat the good things of the land and leave it as an inheritance to your children forever.’

Now while Ezra was praying and confessing, weeping and laying himself face down before the house of God, a very large group from Israel, of men, women, and children, gathered to him, for the people wept bitterly.

Therefore let us now make a covenant with our God to send away all the [foreign] wives and their children, in accordance with the advice of my lord and of those who tremble [in reverent obedience] at the commandment of our God; and let it be done in accordance with the Law.

All these had married foreign women, and some of them had wives by whom they had children.
