“Where is the way to the dwelling of light, and where is the place of darkness,
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
Where is the way where light dwelleth?.... Or the way to the place where it dwells, and what that is; and as for darkness, where is the place thereof? where these were placed when they were first separated at the creation? where light goes and dwells, when it departs from us at sun setting? and where the darkness betakes itself, and makes its abode at sun rising?
The marvels in heaven. "What is the way (to the place wherein) light dwelleth?" The origin of light and darkness. In Gen 1:3-5, Gen 1:14-18, "light" is created distinct from, and previous to, light-emitting bodies, the luminaries of heaven.
