'Unicorn' in the Bible

God brought them out of Egypt; he hath as it were the strength of an unicorn.

God brought him forth out of Egypt; he hath as it were the strength of an unicorn: he shall eat up the nations his enemies, and shall break their bones, and pierce them through with his arrows.

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?

He maketh them also to skip like a calf; Lebanon and Sirion like a young unicorn.

But my horn shalt thou exalt like the horn of an unicorn: I shall be anointed with fresh oil.
