8. Draw nigh to God--So "cleave unto Him," De 30:20, namely, by prayerfully (Jas 4:2, 3) "resisting Satan," who would oppose our access to God.
      he will draw nigh--propitious.
      Cleanse . . . hands--the outward instruments of action. None but the clean-handed can ascend into the hill of the Lord (justified through Christ, who alone was perfectly so, and as such "ascended" thither).
      purify . . . hearts--literally "make chaste" of your spiritual adultery (Jas 4:4, that is, worldliness) "your hearts": the inward source of all impurity.
      double-minded--divided between God and the world. The "double-minded" is at fault in heart; the sinner in his hands likewise.
