Was for song, Heb. was for lifting up; either,
1. Of the ark; he was for carriage of the ark, being appointed to instruct or direct the time and manner of carrying the ark, and when they should make a stand or a change in the bearers. Or rather,
2. Of the voice; he was the moderator of the music, instructing them when and how to lift up their voices, or change their notes, or make their stops, which best agrees with the following reason, because he was skillful; for this required far more skill than the carriage of the ark, which any man of common discretion could easily govern; and with 1 Chronicles 15:27, where this same Chenaniah is joined with the singers.
