The principle of children caring for their parents (and parents caring for their children) runs throughout the Bible. Here is a selection of passages:
Honor your father and your mother, that your days may be long in the land that the LORD your God is giving you.
He who does violence to his father and chases away his mother is a son who brings shame and reproach.
If one curses his father or his mother, his lamp will be put out in utter darkness.
Listen to your father who gave you life, and do not despise your mother when she is old.
Children, obey your parents in the Lord, for this is right. “Honor your father and mother” (this is the first commandment with a promise), “that it may go well with you and that you may live long in the land.” Fathers, do not provoke your children to anger, but bring them up in the discipline and instruction of the Lord.
Think especially of the way Jesus cared for his mother and made sure she was provided for (see John 19:27).
