1 Chronicles 15:16

And David spake to the chief of the Levites to appoint their brethren to be the singers with instruments of musick, psalteries and harps and cymbals, sounding, by lifting up the voice with joy.

. David spake ... appoint ... singers with instruments. These eminent Levites were instructed to train the musicians and singers who were under them for the solemn procession. The performers were ranged in three choirs or bands, and the names of the principal leaders are given, 1 Chronicles 15:17; 1 Chronicles 15:21, with the instruments respectively used by each х nªbaaliym (H5035) wªkinorowt (H3658) uwmtsiltaayim (H4700), psalteries, and harps, and cymbals. Josephus says that these instruments were made of electrum, a precious alloy of gold, of a pale yellow colour]. Ben, 1 Chronicles 15:18, is omitted in 1 Chronicles 15:20. Either it was used merely as a common noun, to intimate that Zechariah was the son of Jaaziel or Aziel, or Ben is the same as Azaziah.
