Job 1:2-4

2 And he had seven sons and three daughters.

3 And of cattle he had seven thousand sheep and goats, and three thousand camels, and a thousand oxen, and five hundred she-asses, and a very great number of servants. And the man was greater than any of the sons of the east.

4 His sons regularly went to one another's houses, and every one on his day gave a feast: and at these times they sent for their three sisters to take part in their feasts with them.
