All these were under the hands of their father, for song in the house of the Lord,.... Instructed and directed by him in the performance of the service in the temple:

with cymbals, psalteries, and harps, for the service of the house of God; which were the three principal instruments of music used in the temple service:

according to the king's order, to Asaph, Jeduthun, and Heman; who ordered and directed them what to sing, what tunes to make use of, and what instruments to play upon to those tunes.

1 Chronicles 25:6 is the subscription to the enumeration, 1 Chronicles 25:2-5. כּל־אלּה are not the fourteen sons of Heman, but all the sons of Asaph, Jeduthun, and Heman. All these were under the direction of their fathers for song in the house of Jahve, with cymbals ... for the service in the house of God under the direction of the king, etc. אביהם is used distributively of each father of the sons named. Bertheau supplies after אביהם the name Heman, and thereby the first half of the verse contradicts the second, which he correctly understands to refer to the twenty-four persons enumerated. - In 1 Chronicles 25:7 the total number is given. Their number (the number) of the sons of Asaph, Jeduthun, and Heman (i.e., of the twenty-four 4 + 6 + 14 mentioned by name), with their brethren, was 288 (24 x 12); whence we learn that each of those named had eleven אחים, all of them שׁיר מלמּדי שׁיר, learned, practised in song for Jahve. In כּל־המּבין the sons and the brothers are both included, in order to give the total number. מבין, having understanding, knowledge of a thing, denotes here those who by education and practice were skilled in song - the accomplished musicians. Their number was 288, and these were divided into twenty-four choirs (classes). David had, according to 1 Chronicles 23:5, appointed 4000 Levites for the performance of the music. Of these, 288 were מבינים skilled in song; the others were scholars (תּלמידים), as 1 Chronicles 25:8 shows, where מבין and תּלמיד are the two categories into which the musicians are divided.

All these were under the hands of their father for song in the house of the LORD, with cymbals, psalteries, and harps, for the service of the house of God, according to the king's order to Asaph, Jeduthun, and Heman.

according...: Heb. by the hands of the king

6, 7. All these were under the hands of their father-Asaph had four sons, Jeduthun six, and Heman fourteen, equal to twenty-four; making the musicians with their brethren the singers, an amount of two hundred eighty-eight. For, like the priests and Levites, they were divided into twenty-four courses of twelve men each, equal to two hundred eighty-eight, who served a week in rotation; and these, half of whom officiated every week with a proportionate number of assistants, were skilful and experienced musicians, capable of leading and instructing the general musical corps, which comprised no less than four thousand (1Ch 23:5).

25:1-31 The singers and musicians. - David put those in order who were appointed to be singers and musicians in the temple. To prophesy, in this place, means praising God with great earnestness and devout affections, under the influences of the Holy Spirit. In raising these affections, poetry and music were employed. If the Spirit of God do not put life and fervour into our devotions, they will, however ordered, be a lifeless, worthless form.
