And it was so, when the days of the feasting were gone about, that Job sent and hallowed them; and he rose up early in the morning, and offered up burnt-offerings [according to] the number of them all; for Job said, It may be that my children have sinned, and cursed God in their hearts. Thus did Job continually.
When a period of feasting had run its course, Job would make arrangements for them to be purified. Early in the morning he would sacrifice a burnt offering for each of them, thinking, “Perhaps my children have sinned and cursed God in their hearts.” This was Job’s regular custom.
