'Children' in the Bible

I, a ruler in the church, send word to the noble sister who is of God's selection, and to her children, for whom I have true love; and not only I, but all who have knowledge of what is true;

It gave me great joy to see some of your children walking in the true way, even as we were ordered to do by the Father.

The children of your noble sister, who is of God's selection, send you their love.
