Ps 43:1
43:1 Judge {a} me, O God, and plead my cause against an ungodly
     {b} nation: O deliver me from the deceitful and unjust man.

     (a) He desires God to undertake his cause against the
         enemies but chiefly that he would restore him to the
         tabernacle.
     (b) That is, the cruel company of my enemies.

Ps 43:3
43:3 O send out thy {c} light and thy truth: let them lead me;
     let them bring me unto thy holy hill, and to thy
     tabernacles.

     (c) That is, your favour which appears by the performance
         of your promises.

Ps 43:4
43:4 Then {d} will I go unto the altar of God, unto God my
     exceeding joy: yea, upon the harp will I praise thee, O God
     my God.

     (d) He promises to offer a solemn sacrifice of thanksgiving
         in token of his great deliverance.

Ps 43:5
43:5 Why art thou cast down, O my soul? and why art thou
     disquieted within me? {e} hope in God: for I shall yet
     praise him, [who is] the health of my countenance, and my
     God.

     (e) By which he admonishes the faithful not to relent but
         constantly to wait on the Lord, though their troubles
         are long and great.
