Job 1:4-5

⁴His sons went and held a feast in the house of each one on his birthday; and they sent and called for their three sisters to eat and to drink with them. ⁵It was so, when the days of their feasting had run their course, that Job sent and sanctified them, and rose up early in the morning, and offered burnt offerings according to the number of them all. For Job said, "It may be that my sons have sinned, and renounced God in their hearts." Thus did Job continually.
