Job 39:2

Canst thou number the months, &c.— The meaning of these questions is, "Knowest thou the time and circumstances of their bringing forth?" For, to know the time only was easy, and had nothing in it extraordinary; but the circumstances had something peculiarly expressive of God's providence, which makes the question proper in this place. Pliny observes, that the hind with young is by instinct directed to a certain herb called seselis, which facilitates the birth. Thunder also, which looks like the more immediate hand of Providence, has the same effect. Dr. Young.
