Let their eyes be darkened, so that they cannot see, and make their loins tremble continually.
PSALM 69 There is a close resemblance between this psalm and the twenty-second. In the opening verses, David complains of the barbarous cruelty of his enemies, and of the grievous wrongs which they had inflicted upon him. The particular enemies of whom he speaks are uncertain; some referring the occasion of the composition of the psalm to his persecution by Saul, and others to the rebellion of Absalom.
Commenting on Psalm 69:1-36
Let their eyes be darkened, that they see not. They shall wander in a darkness that may be felt. They have loved darkness rather than light, and in darkness they shall abide. Judicial blindness fell upon Israel after our Lord's death and their persecution of his apostles; they were blinded by the light which they would not accept.
These imprecations are not David's prayers against his enemies, but prophecies of the destruction of Christ's persecutors, especially the Jewish nation, which our Lord himself foretold with tears, and which was accomplished about forty years after the death of Christ.
