The enormity of Jerusalem’ s sins which reached unto heaven are underlined in verses five and six in the exercise of the prerogatives that belongs only to God--“ Vengeance is mine, I will repay, saith the Lord” --He remembered her iniquities, and rendered due reward double unto double, according to her works. Again, it was Lord’ s answer to the altar cry of martyrs in chapter 6:10, “ how long, 0 Lord, holy and true, dost thou not judge and avenge our blood on them that dwell on the earth.”
