He discovereth deep things out of darkness. By "deep things" are probably meant the "deeply laid schemes" which wicked men concoct in darkness (or secrecy). These God often "discovers," or causes to be laid bare.
English history can point to such a case in the discovery of the famous "Gunpowder Plot" in the second year of King James I. And bringeth out to light the shadow of death. There is nothing secret which God cannot, if he choose, reveal; nor is there anything hid which he cannot make known.
Dark, murderous schemes, on which lies a shadow as of death, which men plan in secret, and keep hidden in their inmost thoughts, he can, and often does, cause to be brought to light and made manifest in the sight of all.
Every such scheme, however carefully guarded and concealed, shall be one day made known (Matthew 10:26). Many are laid bare even in the lifetime of their devisers.
