   It is generally supposed that this Psalm was composed by
   David, when persecuted by Saul, who was rendered more
   implacable by the base and malicious calumnies of Doeg and
   others; though some are of opinion, that it was written when
   David fled from Absalom, and that Ahithophel, rather than
   Doeg, is the typical person against whom it is principally
   directed.
