[30:21] 1 tn Heb “and they were praising the Lord day by day, the Levites and the priests with instruments of strength to the Lord.” The phrase בִּכְלֵי־עֹז (bikhley-’oz, “with instruments of strength”) might refer to loud sounding musical instruments (NASB “with loud instruments”; NEB “with unrestrained fervour”). The present translation assumes an emendation to בְּכָל־עֹז (bÿkhol-’oz, “with all strength”); see 1 Chr 13:8, as well as HALOT 805 s.v. I עֹז and BDB 739 s.v. עֹז).
