'Children' in the Bible

Now while Ezra was praying and making confession, weeping and prostrating himself before the house of God, a very large assembly, men, women and children, gathered to him from Israel; for the people wept bitterly.

So now let us make a covenant with our God to put away all the wives and their children, according to the counsel of my lord and of those who tremble at the commandment of our God; and let it be done according to the law.

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