John Gill

Wickedness is in the midst thereof,.... All manner of wickedness; abominable wickedness; wickedness as arrived to its highest pitch, and as having filled up its measure; see Eze 9:4; deceit and guile depart not from her streets; where truth was fallen, and equity could not enter, Isa 59:14; for these are contrary the one to the other, and are incompatible; where the one prevails, the other must give way. This whole account shows the aboundings of sin in Jerusalem at this time, and that it was openly and publicly committed, and contains so many reasons of the imprecations in Psa 55:9.
