Job 1:4-5

His 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. [Gen 21:8; 40:20] When 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.
