Job 1:4-5

4Each of Job's sons would give parties for each other in their homes. They sent messages to their three sisters to come and eat the feast with them.

5After each party, Job would ask his children to come and visit him. He wanted to make them clean again if they were guilty of bad things. He thought, ‘Perhaps they have done something that is bad. Perhaps they have thought bad things against God.’ So he would get up early in the morning. He would offer a burnt offering as a sacrifice for each of his children. Job always did this after each party that his children had.
