1 Timothy 5:1-4

Rebuke not an elder, but exhort him as a father; the younger men as brethren: the elder women as mothers; the younger as sisters, in all purity. Honor widows that are widows indeed. But if any widow hath children or grandchildren, let them learn first to show piety towards their own family, and to requite their parents: for this is acceptable in the sight of God.
