Matthew Henry Commentary Psalms 124:1-5

"If it had not been Jehovah who was on our side, Let Israel now say, If it had not been Jehovah who was on our side, When men rose up against us; Then they had swallowed us up alive, When their wrath was kindled against us; Then the waters had overwhelmed us, The stream had gone over our soul; Then the proud waters had gone over our soul." — Psalms 124:1-5 (ASV)

God allows the enemies of His people sometimes to prevail greatly against them, so that His power may be more clearly seen in their deliverance. Happy the people whose God is Jehovah, a God all-sufficient. Besides applying this to any particular deliverance accomplished in our own times and in ancient times, we should also remember the great work of redemption by Jesus Christ, by which believers were rescued from Satan.
