Job 1
4 Ref 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.
5 Ref And at the end of their days of feasting, Job sent and made them clean, getting up early in the morning and offering burned offerings for them all. For, Job said, It may be that my sons have done wrong and said evil of God in their hearts. And Job did this whenever the feasts came round.
