Summary

Arukh ha-Shulchan/Orach Chaim/240

Honoring ones parents is so great that it overrides His (G-D's) Honor. As it says there "Honor (your mother and father) " and it says (concerning honoring G-D) , "Honor G-D from your wealth"- With what (is one required to honor G-D with) ?- "with your wealth"- i.e. with your money. But concerning the honor (that one is required to show towards ones parents) - whether one has money or not- one is required to honor them- even if he has to feed the pigs (to honor them) We will, G-D willing, elaborate on this in section 18.
