Job 1:4-6

4 Job's sons used to take turns giving a feast, to which all the others would come, and they always invited their three sisters to join them.

5 The morning after each feast, Job would get up early and offer sacrifices for each of his children in order to purify them. He always did this because he thought that one of them might have sinned by insulting God unintentionally.

6 When the day came for the heavenly beings to appear before the LORD, Satan was there among them.
