What did God tell Job's friends to offer as a burnt offering?

Answer: Seven bulls and seven rams

God told Eliphaz and his friends to take seven bulls and seven rams to Job and offer a burnt offering, and Job would pray for them.

“So now, take seven bulls and seven rams, go to My servant Job, and sacrifice a burnt offering for yourselves. Then My servant Job will pray for you, for I will accept his prayer and not deal with you according to your folly. For you have not spoken accurately about Me, as My servant Job has.””— Job 42:8 (BSB)
