Iniquities prevail against us

David speaks about iniquity as if it were a person that is able to defeat or oppress. Alternate translation: "It is as if our own sins were defeating us" (See: rc://en/ta/man/jit/figs-personification)

you will forgive them

The word "them" refers to our "iniquities."
