Keil & Delitzsch, on Lam 3:52

“Sade. My enemies have chased me and caught me like a bird, without cause.”

“His pain and sorrow over the sad condition of the people recall to his memory the persecutions and sufferings which the godly have endured. The figure, "They who without cause are mine enemies have hunted me like a bird," is an imitation of Psa 11:1. איבי חנּם reminds one of שׂנאי , Psa 35:19 and Psa 69:5. But the prophet prefers איבי to שׂנאי, lest any one should restrict the words to persecutions which arose out of personal hatred.”
