Job 1:4-5

4Now it was customary for his sons to hold a banquet, each on his own day in his own house. They would send to invite their three sisters to eat and drink with them.

5When the round of banquet days was completed, Job would send for them and consecrate them. He would rise early in the morning and offer burnt offerings, according to the number of them all. For Job said, “Perhaps my children have sinned and cursed God in their hearts.” Thus Job did everyday.
