Psalms 69:23-29

Verse 27

Add iniquity unto their iniquity - תנה עון על עונם tenah avon al avonam; give iniquity, that is, the reward of it, upon or for their iniquity. Or, as the original signifies perverseness, treat their perverseness with perverseness: act, in thy judgments, as crookedly towards them as they dealt crookedly towards thee. They shall get, in the way of punishment, what they have dealt out in the way of oppression.
Verse 28

Let them be blotted out - They shall be blotted out from the land of the living. They shall be cut off from life, which they have forfeited by their cruelty and oppression. The psalmist is speaking of retributive justice; and in this sense all these passages are to be understood.

And not be written with the righteous - They shall have no title to that long life which God has promised to his followers.
Verse 29

I am poor and sorrowful - Literally, I an laid low, and full of pain or grief. Hence the prayer, "Let thy salvation, O God set me on high!" My oppression has laid me low; thy salvation shall make me high!
