Job 28:3

He (God) hath, &c. (Haydock) --- Darkness, before which these inventions could not be made; (Menochius) or, man has been able to measure the hours of day and night by the shadow of the sun, and by other means. He always strives to perfect his works, and examines with care the mines which lay concealed in the most profound obscurity. (Calmet) --- Precious stones and metals lie the deepest. (Menochius) --- From the consideration of these beautiful works, men ought to raise their minds to the Creator, and wisely rest in him alone. (Worthington)
