Job 39:9KJV

7He scorneth the multitude of the city, neither regardeth he the crying of the driver.

8The range of the mountains his pasture, and he searcheth after every green thing.

9Will the unicorn be willing to serve thee, or abide by thy crib?

10Canst thou bind the unicorn with his band in the furrow? or will he harrow the valleys after thee?

11Wilt thou trust him, because his strength great? or wilt thou leave thy labour to him?
