Job 1:4-5

His sons used to go and hold a feast in the house of each one on his day, and they would send and invite their three sisters to eat and drink with them. When the days of feasting had completed their cycle, Job would send and consecrate them, rising up early in the morning and offering burnt offerings according to the number of them all; for Job said, “Perhaps my sons have sinned and cursed God in their hearts.” Thus Job did continually.
