Have the gates of death been revealed to you? Have you seen the gates of the shadow of death?
The Lord here proceeds to ask Job many puzzling questions, to convince him of his ignorance, and so to shame him for his folly in prescribing to God. If we will but try ourselves with such interrogatories as these, we shall soon be brought to own that what we know is nothing in comparison with what we know not.
Commenting on Job 38:12-24
Have the gates of death been opened unto thee?.... Meaning not by which death has entered into the world, and which have been the causes and occasion of it; as the sin of man, the appointment of God, and various providences, calamities and diseases; but by which men enter into the state of the dead.
seen--The second clause heightens the thought in the first. Man during life does not even "see" the gates of the realm of the dead ("death," Job 10:21); much less are they "opened" to him. But those are "naked before God" (Job 26:6).
