Job 1:4-5

4His sons used to take turns having banquets at their homes. They would send an invitation to their three sisters to eat and drink with them.

5Whenever a round of banqueting was over, Job would send for his children and purify them, rising early in the morning to offer burnt offerings for all of them. For Job thought, “Perhaps my children have sinned, having cursed God in their hearts.” This was Job’s regular practice.
