Was not the sin of Peor enough for us? Up to this very day we have not cleansed ourselves from that sin, even though a plague fell on the community of the LORD!
NIV
Is the iniquity of Peor too little for us, from which we are not cleansed even now, although there came a plague [in which 24,000 died] in the congregation of the Lord, [Num. 25:1-9.]AMP
Is the iniquity of Peor too little for us, from which we are not cleansed until this day, although there was a plague in the congregation of the LORD,
