Charles Ellicott Commentary Lamentations 3:58

"O Lord, thou hast pleaded the causes of my soul; thou hast redeemed my life." — Lamentations 3:58 (ASV)

Thou hast pleaded the causes of my soul—i.e., Jehovah had appeared as the advocate, or next-of-kin protector, of the prophet in the persecutions which were aimed against his life. Another personal reference to the prophet’s sufferings. (Jeremiah 37:14; Jeremiah 38:4.)
