And Chenaniah chief of the Levites was for song
 But the chief for the song were Heman, Asaph, and Ethan; rather 
 for the burden,
 as the Targum; for the lifting up and bearing the ark: 
 he instructed about the song;
 or about the taking up and bearing the burden, the ark; directing when to take it up, and how far to go with it, and then rest: 
 because he was skilful;
 a wise and prudent man in all things, and so proper to direct in this business.
