A Psalm of David. Judge me, O LORD; for I have walked in mine integrity: I have trusted also in the LORD; therefore I shall not slide. Judge me, O Lord - There are so many strong assertions in this Psalm concerning the innocence and uprightness of its author that many suppose he wrote it to vindicate himself from some severe reflections on his conduct or accusations relative to plots, conspiracies, etc. This seems to render the opinion probable that attributes it to David during his exile, when all manner of false accusations were brought against him at the court of Saul.
I have walked in mine integrity - I have never plotted against the life nor property of any man; I have neither coveted nor endeavored to possess myself of Saul's crown.
I have trusted - Had I acted otherwise, I could not have been prosperous, for thou wouldst not have worked miracles for the preservation of a wicked man.
I shall not slide - I shall be preserved from swerving from the paths of righteousness and truth.
