Job 1:2-4

2And seven sons and three daughters were born to him.

3Also, his possessions were seven thousand sheep, three thousand camels, five hundred yoke of oxen, five hundred female donkeys, and a very large household, so that this man was the greatest of all the people of the East.

4And his sons would go and feast in their houses, each on his appointed day, and would send and invite their three sisters to eat and drink with them.
