What constitutes honor? One must provide them with food and drink, clothing and garments, to conduct them home and take them out, and rise before them. And one must provide them with all their needs cheerfully: even if one should feed them daily the most delectable foods but does so with ill grace, one incurs Divine punishment.

One must perform for parents all such services as a servant performs for his master; and one is duty bound to render personal services even at personal expense.

To what lengths should the duty of honoring parents go? Even were they to take his purse full of gold, and cast it into the sea in his presence, he must not shame them, manifest grief in their presence, or display any anger, but accept the Divine decree without demur! [Shulchan Aruch, ibid, 240:4ff.]
