'Widow' in the Bible

But if a widow has children or grandchildren [who are adults], see to it that these first learn to show great respect to their own family [as their religious duty and natural obligation], and to compensate their parents or grandparents [for their upbringing]; for this is acceptable and pleasing in the sight of God.

Now a woman who is really a widow and has been left [entirely] alone [without adequate income] trusts in God and continues in supplications and prayers night and day.
