Ver. 38 And Obededom, with their brethren, threescore and eight,.... The Levites, the brethren of Asaph and Obededom, these were left before the ark to minister there:
Obededom also the son of Jeduthun; or Ethan, which some take to be another Obededom; but the ו, "vau" may be explanative, "even Obededom":
and Hosah to be porters; these he left to be doorkeepers of the ark.
