Job 39:10-13

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.

12It will not help you to bring in your harvest of grain. It will not take the grain to your threshing floor.

13When an ostrich is happy, it waves its wings. But it cannot use its wings to fly, as a stork can do.
