"So long as the power is his [oozo], I shall wait, turned toward You, for G-D is my high tower.  Since He is G-D, Who is merciful [chasdi] to me, He will anticipate me; G-D will let me behold what I expected, upon those that lie in wait for me (Psalm 59:10-11)."   Rav Hirsch explains that David looks upon Saul as an instrument of G-D.   The word "oozo" is the equivalent of "oz lo", meaning " as long as the power is his (Saul’s)."  David understands the value of patience, of accepting that Saul’s power has been granted to him by G-D.  This patience permits him to take the long-term view; it allows him to let go of his human need to control and to instead let go and let G-D.   Therefore, David turns to Hashem, who is the judge of both Saul and David, and suspends action.   David’s trust in Hashem is absolute, for He is his high tower, who has continually sustained and protected him.  David continues his thought by affirming that Hashem is the G-D of mercy, who will anticipate his needs, and act to bring swift justice to those that lie in wait for him.
