John Gill Commentary Psalms 136:24

"And hath delivered us from our adversaries; For his lovingkindness [endureth] for ever:" — Psalms 136:24 (ASV)

And has redeemed us from our enemies Temporal enemies, tyrants, and oppressors: and spiritual ones, sin, Satan, the world, the law, death, and hell;

for his mercy [endures] for ever; as is clearly seen in redemption by Jesus Christ, where mercy and truth have met together; and which is a distinguishing mercy to the sons of men, not granted to angels.
