Job 1:4-5

4Job’s sons would take turns preparing feasts in their homes, and they would also invite their three sisters to celebrate with them.

5When these celebrations ended—sometimes after several days—Job would purify his children. He would get up early in the morning and offer a burnt offering for each of them. For Job said to himself, “Perhaps my children have sinned and have cursed God in their hearts.” This was Job’s regular practice.
