Can you hold him to the furrow with a harness? Will he plow the valleys behind you?
God here shows Job what little acquaintance he had with the untamed creatures that run wild in the deserts and live at large, but are the care of the divine Providence. As, I. The wild goats and the hinds. That which is taken notice of concerning them is the bringing forth and bringing up of their young ones.
Commenting on Job 39:1-12
Canst thou bind the unicorn with his band in the furrow?.... Put the yoke and harness upon him, and fasten it to the plough to draw it, that he may make furrows with it in the field, or plough up the ground as the tame ox does? thou canst not; or will he harrow the valleys after thee?
his band--fastened to the horns, as its chief strength lies in the head and shoulders. after thee--obedient to thee; willing to follow, instead of being goaded on before thee.
