Job 39:9-12King James Version (KJV)
9 Will the unicorn be willing to serve thee, or abide by thy crib?
10 Canst thou bind the unicorn with his band in the furrow? or will he harrow the valleys after thee?
11 Wilt thou trust him, because his strength is great? or wilt thou leave thy labour to him?
12 Wilt thou believe him, that he will bring home thy seed, and gather it into thy barn?
