The Extent of Honoring Parents

The amoraim once asked a rabbi: "What is the extent of the mitzvh of respecting ones parents?" Rabbi ulla told them to see what goys did in ashkelon: Dama ben netina refused substantial payment in order to not disturb his sleeping father. The sage requested one of the cohen gadol's breastplate gemstones and he declined the eight hundred thousand gold dinar as he didnt want to wake up his father. Hashem rewarded him for this with a red heifer.
