The refrain theme comes from Old Testament passages in which praise to God for his acts of deliverance was often shouted, both literally and metaphorically, from the mountaintops (Isa. 42:11). While the three stanzas tell the essence of the Christmas story, the refrain underscores the missionary impetus of the Christian church: "go and make disciples of all nations" (Matt. 28:19). The "go, tell," which initially applied to the singers caroling on the university campus, is a signal for us to leave the comfortable confines of Christian worship and "go, tell" the message of Christ's redemption to the whole world.
the verses of these songs were published by John Work, II, in place of the original ones which could not be found. In 1940 John Work, III, had the songs copyrighted and published in his book American Negro Songs.-Companion to the United Methodist Hymnal, p. 360
