INTRODUCTION TO PSALM 26 Psalm of David. The occasion of this psalm seems to be the quarrel between Saul and David, the former listening to calumnies and reproaches cast upon the latter, and persecuting him in a violent manner. The argument of it is the same, in a great measure, with the seventh psalm, and is an appeal made to God, the Judge of the whole earth, by the psalmist, for his innocence and integrity; Theodoret thinks it was written by David when he fled from Saul.
