Job 1:4-5

4His sons used to go [in turn] and feast in the house of each one on his day, and they would send word and invite their three sisters to eat and drink with them.

5When the days of their feasting were over, Job would send [for them] and consecrate them, rising early in the morning and offering 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.” Job did this at all [such] times.
