1 Timothy 5:3-4 NKJV
Honor widows who are really widows. 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.

James 1:27 NCV

Religion that God accepts as pure and without fault is this: caring for orphans or widows who need help, and keeping yourself free from the world’s evil influence. 

1 Timothy 5:8 NKJV
But if anyone does not provide for his own, and especially for those of his household, he has denied the faith and is worse than an unbeliever.
