Job 1:5; Job 42:8

Job 1:5

5 When a period of feasting had run its course, Job would make arrangements for them to be purified. Early in the morning he would sacrifice a burnt offering for each of them, thinking, “Perhaps my children have sinned and cursed God in their hearts.” This was Job’s regular custom.

Job 42:8

8 So now take seven bulls and seven rams and go to my servant Job and sacrifice a burnt offering for yourselves. My servant Job will pray for you, and I will accept his prayer and not deal with you according to your folly. You have not spoken the truth about me, as my servant Job has.”
