Why did the patriarch Job offer burnt offerings?

Answer

"And his sons went and feasted in their houses, every one his day; and sent and called for their three sisters
to eat and to drink with them. And it was so, when the days of their feasting were gone about, that Job sent
and sanctified them, and rose up early in the morning, and offered burnt offerings according to the number
of them all: for Job said, It may be that my sons have sinned, and cursed God in their hearts. Thus did Job
continually." Job 1: 4, 5.
