Job 1:3-5

His substance also was seven thousand sheep, and three thousand camels, and five hundred yoke of oxen, and five hundred she-asses, and a very great household; so that this man was the greatest of all the children of the east. And his sons went and held a feast in the house of each one upon his day; and they sent and called for their three sisters to eat and to drink with them. And it was so, when the days of their feasting were gone about, 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.
