Job 39:7-11

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

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

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

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

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