NOTES for Psa 69
The image of a person unjustly persecuted and finding no place for himself amid oppression has long been interpreted as one of the prophetic images of the suffering Messiah. There is every reason for this: many details depicted in the psalm were fulfilled in the Savior’s earthly life, down to the gall and vinegar He was given to drink.
Nevertheless, we cannot completely identify the man who describes his sufferings with the coming Messiah, because of, for example, his self-critical admission: “O God, You know my folly; the wrongs I have done are not hidden from You.” This man does not deny his guilt and sins; he acknowledges and confesses them. Yet even without considering himself blameless, he continues to hope in the Lord, all the more because the existence of his sins does not make his persecutors agents of justice.
One might say that the two readings of the psalm contradict one another. But the contradiction is resolved by the reality of Golgotha, where the Savior atoned for our sins by sharing the suffering of all who have had to endure it, and therefore also the suffering of the author of this psalm.
