Adam Clarke on Psalms 69:4

Then I restored that which I took not away - I think, with Calmet, that this is a sort of proverbial expression, like such as these, "Those who suffered the wrong, pay the costs." Delirant reges, plectuntur Achivi. "Kings sin, and the people are punished." "The fathers have eaten sour grapes, and the children's teeth are set on edge." Our fathers have grievously sinned against the Lord, and we their posterity suffer for it. See on Psa 69:12 (note). Some have applied it to our Lord. I restored, by my suffering and death, that image of God and the Divine favor, which I took not away. That is, In my human nature I expiated the crime that human beings had committed against God. But such applications are very gratuitous.
