1 Timothy 5:4-5, 9-11, 16

But if a widow has children or grandchildren, let them first learn to show godliness to their own household and to make some return to their parents, for this is pleasing in the sight of God. She who is truly a widow, left all alone, has set her hope on God and continues in supplications and prayers night and day

Let a widow be enrolled if she is not less than sixty years of age, having been the wife of one husband, and having a reputation for good works: if she has brought up children, has shown hospitality, has washed the feet of the saints, has cared for the afflicted, and has devoted herself to every good work. But refuse to enroll younger widows, for when their passions draw them away from Christ, they desire to marry

If any believing woman has relatives who are widows, let her care for them. Let the church not be burdened, so that it may care for those who are truly widows.
