They search out iniquities; they accomplish a diligent search: both the inward [thought] of every one [of them], and the heart, [is] deep.
Ver. 6. They search out iniquities] Abstrusissima quaeque exquisierunt; they search the devil's skull for new inventions; who is ready enough to lend them his seven heads to plot and his ten horns to push at good people. How wittily wicked was Saul to destroy David, if he could have done it! See his counsel to the Ziphites, 1 Samuel 23:22 .
They accomplish a diligent search] Heb. a search searched, i.e. They seek out all occasions, they try all tricks, they do all that can be done to undo me. Whereunto he fitly subjoineth this epiphonema by way of exclamation, Adeo intimum viri et cor profundum est, So deep is the inward part and heart of man (for so I read it)! so deep and fathomless, so deceitful, and desperately wicked.
