Lamentations 3:7

New English Translation

⁷He has walled me in^[a] so that I cannot get out;
he has weighted me down with heavy prison chains.^[b]

Lamentations 3:7 tn The verb גָּדַר (gadar) has a twofold range of meaning: (1) “to build up a wall” with stones, and (2) “to block a road” with a wall of stones. The imagery either depicts the Lord building a wall to seal off personified Jerusalem with no way to escape the city, or his blocking her road of escape. Siege imagery prevails in 3:4-6, but 3:7-9 pictures an unsuccessful escape that is thwarted due to blocked roads in 3:7 and 3:9.
Lamentations 3:7 tn Heb “he has made heavy my chains.”
