Matthew Poole and continuators on Job 39:10

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

i. e. In thy furrowed Field, by a Metonymy. Or, to or for (as the prefix Beth is oft used, as Gen. 1. 4. Levit 16. 22. Iob 24. 5.) the furrow, i. e. to make Furrows, or to Plow: for which work Cattle use to be bound together that they may be directed by the Husbandman, and may make right Furrows.

To wit, the low grounds; which are most proper for, and most imployed in the work of Plowing.

Under thy conduct following thee step by step.
