Iyov 1:5

And it was so, when the yamim of their mishteh were gone, that Iyov sent and set them apart as kodesh, and rose up early in the boker, and offered olot (burnt offerings) according to the mispar (number) of them all: for Iyov said, It may be that my banim have sinned, and cursed Elohim in their hearts. Thus did Iyov kol hayamim.
