This psalm is without a title; but may well enough be thought to be one of David's: and the Septuagint, Vulgate Latin, Ethiopic, and Syriac versions, call it a psalm of David, and the latter adds, when Jonathan told him that Saul intended to kill him; and certain it is, that it was wrote by the same person, at the same time, and upon the same occasion as the preceding, seeing some of the same expressions are used in it, see Ps 42:1, title; and some take this and the preceding to be but one psalm, and this might be written with that on account of the rebellion of his son Absalom.
Ver. 1. Judge me, O God,.... The Targum adds, with the judgment of truth; see Ro 2:2;and plead my cause; which was a righteous one; and therefore he could commit it to God to be tried and judged by him, and could put it into his hands to plead it for him; See Gill on "Ps 35:1";against an ungodly nation; meaning either the Philistines, among whom he was; or his own nation, when they joined his son Absalom in rebellion against him: some understand it of the great numbers that were with Saul, when he was persecuted by him;O deliver me from the deceitful and unjust man; either Absalom, who, under pretence of a vow he had vowed in Hebron, got leave of David to go thither, and then engaged in a conspiracy against him; or Ahithophel, who had been his friend and acquaintance, but now joined with Absalom.
