And when the days of feasting were over, Job would send for his children to purify them, rising early in the morning to offer burnt offerings for all of them. For Job thought, “Perhaps my children have sinned and cursed God in their hearts.” This was Job’s regular practice.
Jewish Publication Society of America Version (JPS1917) - Job 1:5 >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 blasphemed God in their hearts.' Thus did Job continually.
