Job's sons would take turns holding feasts in their homes, and they would invite their three sisters to eat and drink with them.

Job 1:3
and he owned 7,000 sheep, 3,000 camels, 500 yoke of oxen, 500 female donkeys, and a very large number of servants. Job was the greatest man of all the people of the East.

Job 1:5
And when the days of feasting were over, Job would send for his children to purify them, rising early in the morning to offer burnt offerings for all of them. For Job thought, "Perhaps my children have sinned and cursed God in their hearts." This was Job's regular practice.

And his sons went and feasted in their houses, every one his day; and sent and called for their three sisters to eat and to drink with them.
