Charles H. Spurgeon on Psalms 78:66

He smote his enemies in the hinder parts. The emerods rendered them ridiculous, and their numerous defeats made them yet more so. They fled but were overtaken and wounded in the back to their eternal disgrace. He put them to a perpetual reproach. Orientals are not very refined, and we can well believe that the haemorrhoids were the subject of many a taunt against the Philistines, as also were their frequent defeats by Israel until at last they were crushed under, never to exist again as a distinct nation.
