Job 39:8-11

8Instead, they live on the hills, where they find fresh plants to eat.

9Can you tell a wild ox to work for you? No! At night, it will not stay to feed at your farm.

10It will not let you tie it to a plough. It will not agree to prepare your fields in the valleys.

11A wild ox is very strong. But you cannot trust it to help you with your difficult work.
