John Trapp on Psalms 69:27

Verſ. 27. Adde iniquity unto their iniquity] Puniſh one ſin with another (by giving them up to a reprobate ſenſe, to an incureable hardneſs) and plague them ſoundly for their fin. The ſame Hebrew word ſignifieth both ſin and puniſhment theſe two are tied together with chains of Adamant.

And let them not come into thy righteouſneſs] i. e. Hold them not righteous, nor beſtow upon them thy crown of righteouſneſs.
