Adam Clarke on 2 Samuel 6:5

On all manner of instruments made of fir wood - This place should be corrected from the parallel place, 1Chr 13:8 : "All Israel played before God, with all their might, and with singing, and with harps, and with psalteries," etc. Instead of בכל עצי bechol atsey, "with all woods" or "trees;" the parallel place is בכל עז bechol oz. "with all their strength:" this makes a good sense, the first makes none. The Septuagint, in this place, has the verse reading; εν ισχυΐ, with might.
