Rashi on Lamentations
Adonoy’s anointed. That is Yoshiyahu, as it is stated in Divrei Hayomim, “And Yirmiyahu lamented over Yoshiyahu.”28II Divrei Hayomim 35:25. See Maseches Ta’anis 22b. Alternatively, ‘Adonoy’s appointed’ refers to Tzidkiyahu king of Yehudah who was blinded and carried off to Bavel in chains by the people of Kasdim.
