Lamentations 4:20

The enemy even captured the Davidic king, Zedekiah, who was as the very breath of life to the Judahites. The Judeans had evidently hoped to live under his authority in captivity, but now he was blind and in prison (Jeremiah 52:7-11).

This section gives three causes for the siege: the sins of the priests and prophets (Lamentations 4:13-16), reliance on foreign alliances (Lamentations 4:17-19), and the capture of Zedekiah (Lamentations 4:20).
