Matthew Henry's Commentary
Judge me, O God, and plead my cause against an ungodly nation: O deliver me from the deceitful and unjust man.
43:6-11 The way to forget our miseries, is to remember the God of our mercies. David saw troubles coming from God's wrath, and that discouraged him. But if one trouble follow hard after another, if all seem to combine for our ruin, let us remember they are all appointed and overruled by the Lord. David regards the Divine favour as the fountain of all the good he looked for. In the Saviour's name let us hope and pray. One word from him will calm every storm, and turn midnight darkness into the light of noon, the bitterest complaints into joyful praises. Our believing expectation of mercy must quicken our prayers for it. At length, is faith came off conqueror, by encouraging him to trust in the name of the Lord, and to stay himself upon his God. He adds, And my God; this thought enabled him to triumph over all his griefs and fears. Let us never think that the God of our life, and the Rock of our salvation, has forgotten us, if we have made his mercy, truth, and power, our refuge. Thus the psalmist strove against his despondency: at last his faith and hope obtained the victory. Let us learn to check all unbelieving doubts and fears. Apply the promise first to ourselves, and then plead it to God.
For thou art the God of my strength: why dost thou cast me off? why go I mourning because of the oppression of the enemy?
O send out thy light and thy truth: let them lead me; let them bring me unto thy holy hill, and to thy tabernacles.
Then 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.
Why art thou cast down, O my soul? and why art thou disquieted within me? hope in God: for I shall yet praise him, who is the health of my countenance, and my God.
