Thou hast rebuked the heathen, thou hast destroyed the wicked, thou hast put out their name for ever and ever.
Thou hast rebuked - not in mere word, as man rebukes, but with actual punishments inflicted; because God's Word shall be operative as a terrible reality to the lost (Psalms 106:9; cf. Psalms 68:30).
The pagan - Hebrew, 'the nations' х gowyim (H1471)] - namely, those confederate against Messiah, of which nations those leagued against David and Israel were the type.
Thou hast destroyed the wicked - Hebrew, singular, 'the wicked one:' the same as the "enemy," next verse.
