Judge me, O God, and plead my cause against an ungodly nation: O deliver me from the deceitful and unjust man.
Nation — So he calls the company of his enemies for their great numbers.
Man — Probably Achitophel or Absalom.
 O send out thy light and thy truth: let them lead me; let them bring me unto thy holy hill, and to thy tabernacles.
Send out — That is, actually discover them.
Truth — Thy favour, or the light of thy countenance, and the truth of thy promises made to me; or the true-light, the illumination of thy spirit, and the direction of thy gracious providence, whereby I may be led in the right way, to thy holy hill.
Hill — Of Zion, the place of God's presence and worship.
