I Timothy 5:4-7, 16

But if any widow has children or grandchildren, let them first learn to show piety at home and to repay their parents; for this is good and acceptable before God. Now she who is really a widow, and left alone, trusts in God and continues in supplications and prayers night and day. But she who lives in pleasure is dead while she lives. And these things command, that they may be blameless.

If any believing man or woman has widows, let them relieve them, and do not let the church be burdened, that it may relieve those who are really widows.
