Job 1:2-4

2Seven sons and three daughters were born to him.

3He also possessed 7,000 sheep, 3,000 camels, 500 yoke (pairs) of oxen, 500 female donkeys, and a very great number of servants, so that this man was the greatest [and wealthiest and most respected] of all the men of the east (northern Arabia).

4His sons used to go [in turn] and 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.
