 By 1921 , Goodman had spoken to Scout leaders in surrounding states about the OA , and lodges were established in a score of Scout councils in the northeast . In October 1921 , he convened the first national meeting of what was then called the National Lodge of the Order of the Arrow in Philadelphia , and Goodman was elected Grand Chieftain . Committees were organized to formulate a constitution , refine ceremonial rituals , devise insignia , and plan future development . Reflecting Goodman 's ongoing interest in music , he composed the words to the Order of the Arrow 's song , " Firm Bound in Brotherhood " , set to the stirring melody of a hymn found in the Presbyterian hymnal of the 1920s , " God the Omnipotent " in 11 @.@ 10 @.@ 11 @.@ 9 meter , which was adapted from the Russian national anthem , " God Save the Tsar ! " , composed by Alexei Lvov in 1833 .
