This confirms what was said (v. 3) concerning God's omnipresence, in order to his judging of evil and good. 1. God knows all things, even those things that are hidden from the eyes of all living: Hell and destruction are before the Lord, not only the centre of the earth, and its subterraneous caverns, but the grave, and all the dead bodies which are there buried out of our sight; they are all before the Lord, all under his eye, so that none of them can be lost or be to seek when they are to be raised again. He knows where every man lies buried, even Moses, even those that are buried in the greatest obscurity; nor needs he any monument with a Hic jacet—Here he lies, to direct him. The place of the damned in particular, and all their torments, which are inexpressible, the state of separate souls in general, and all their circumstances, are under God's eye. The word here used for destruction is Abaddon, which is one of the devil's names, Rev 9 11. That destroyer, though he deceives us, cannot evade or elude the divine cognizance. God examines him whence he comes (Job 1 7), and sees through all his disguises though he is sly, and subtle, and swift, Job 26 6. 2. He knows particularly the hearts of the children of men. If he sees through the depths and wiles of Satan himself, much more can he search men's hearts, though they be deceitful, since they learned all their fraudulent arts of Satan. God is greater than our hearts, and knows them better than we know them ourselves, and therefore is an infallible Judge of every man's character, Heb 4 13.
