Job 1:4-5

4His sons used to go and hold a 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 feasting had completed their cycle, Job would send word to them and consecrate them, getting up early in the morning and offering 1burnt offerings according to the number of them all; for Job said, “2Perhaps my sons have sinned and 3cursed God in their hearts.” Job did so continually.
