1 Chronicles 25:5 Meaning and Commentary

1 Chronicles 25:5

All these were the sons of Heman, the king's seer
The prophet of the king, as the Targum, who was frequently with him, assisting him in the words of God:
in divine things: to lift up the horn;
to blow with the hornpipe or trumpet, and to magnify and set forth the greatness of the kingdom of Israel, and especially of the King Messiah, the horn of salvation, that would be raised up in the house of David: and God gave to Heman fourteen sons;
whose names are before mentioned: and three daughters;
of whom we have no more account, only may observe, that both are the gifts of God, and an heritage from him, ( Psalms 127:3 ) .

3 And the sons of Jeduthun were these; Gedaliah, Zeri, Jeshaiah, (Shimei,) and Hashabiah, and Mattithiah, six; under the hand of their father Jeduthun, that prophesied in an harp, upon men acknowledging and praising the Lord (who prophesied to the accompaniment of a harp, giving thanks, and praising the Lord).

4 Also the sons of Heman were (these of) Heman; Bukkiah, Mattaniah, Uzziel, Shebuel, and Jerimoth, Hananiah, Hanani, Eliathah, Giddalti, and Romamtiezer, and Joshbekashah, Mallothi, Hothir, and Mahazioth;

5 all these the sons of Heman were prophets of the king in the words of God, that he should enhance the horn, or strength. And God gave to Heman fourteen sons and three daughters. (all these were the sons of Heman, the prophet of the king, by the promises of God, to lift up his horn, or his strength. And God gave Heman fourteen sons and three daughters.)

6 All these under the hand of their father were dealed, either assigned, to sing in the temple of the Lord, in cymbals, and psalteries, and harps, into the service of the house of the Lord, nigh the king, that is say, Asaph, and Jeduthun, and Heman. (All these were under the hand, or the power, of their father, and were assigned to play, in the Temple of the Lord, cymbals, and lutes, and harps, for service in the House of the Lord, while Asaph, and Jeduthun, and Heman, were under the direction of the king.)

7 And the number of them, with their brethren that taught the song[s] of the Lord, all the teachers, was two hundred fourscore and eight. (And their number, with their kinsmen who taught the songs of the Lord, yea, all of the teachers, was two hundred and eighty-eight.)
