o come o come immanuuel and ransom captive israel that mourns in lonely exile here until the son of god appear  rejoice rejoice immanuel shall come to thee o israel  o come o come thou lord of might who to thy tribes on sinais height in ancient times didst give the law in cloud and majesty and awe  o come thou rod of jesse free thine own from satans tyranny from depths of hell thy people save and give them victory oer the grave  o come thou dayspring come and cheer our spirits by thine advent here disperse the gloomy clouds of night and deaths dark shadows put to flight  o come thou key of david come and open wide our heavenly home make safe the way that leads on high and close the path to misery
