1 Timothy 5:3-8

Honor and help those widows who are truly widowed [alone, and without support]. 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. Whereas she who lives for pleasure and self-indulgence is spiritually dead even while she still lives. Keep instructing [the people to do] these things as well, so that they may be blameless and beyond reproach. If anyone fails to provide for his own, and especially for those of his own family, he has denied the faith [by disregarding its precepts] and is worse than an unbeliever [who fulfills his obligation in these matters].
