A cause des péchés de ses prophètes, des crimes de ses prêtres, qui versèrent dans son enceinte le sang des innocents,
Tze'enah Ure'enah
“Because of the sins” [4:13]. Because of the sins of the seers and the transgressions of the priests who shed the blood of the righteous.
Rashi
For the sins of her false prophets. [Because of the] false [prophets], this evil has befallen her.18Alternately, ‘because of the sins committed against the prophets,’ namely the murder of Zecharyah, this evil has befallen her. (Eichah Rabbah 4:16) Or ‘because of the sins committed by her prophets and kohanim who burnt incense for idol worship, this evil has befallen her.’ (Targum)
