Psalms 69:27

“iniquity--or, "punishment of iniquity" (Psa 40:12). come . . . righteousness--partake of its benefits.”

“Add iniquity unto their iniquity - Margin, “punishment of iniquity.” The literal rendering is, “Give iniquity upon their iniquity.” Luther understands this as a prayer that “sin may be made a punishment for sin;” that is, that they may, as a punishment for their former sins, be left to commit still more aggravated crimes, and thus draw on themselves severer punishment. So Rosenmuller renders it, “Suffer them to accumulate sins by rushing from one sin to another, until their crimes are matured, and their destined punishment comes upon them.” An idea similar to this occurs in Romans 1:28, where God is represented as having “given the pagan over to a reprobate mind, to do those things which are…”

“Wilt add - Give them up to their own lusts. Not let them - Partake of thy righteousness, or of thy mercy and goodness. Psalms 69:28”
