Charles H. Spurgeon on Psalms 124:6

Blessed be the Lord, who hath not given us as a prey to their teeth. Leaving the metaphor of a boiling flood, he compares the adversaries of Israel to wild beasts who desired to make the godly their prey. Their teeth are prepared to tear, and they regard the godly as their victims. The Lord is heartily praised for not permitting his servants to be devoured when they were between the jaws of the raging ones. It implies that none can harm us till the Lord permits: we cannot be their prey unless the Lord gives us up to them, and that our loving Lord will never do. Hitherto he has refused permission to any foe to destroy us, blessed be his name. The more imminent the danger the more eminent the mercy which would not permit the soul to perish in it. God be blessed for ever for keeping us from the curse. Jehovah be praised for checking the fury of the foe, and saving his own. The verse reads like a merely negative blessing, but no boon can be more positively precious. He has given us to his Son Jesus, and he will never give us to our enemies.
