1 Chronicles 25:7 Meaning and Commentary

1 Chronicles 25:7

So the number of them, with their brethren
Who each of them had twelve with them, as after reckoned: that were instructed in the songs of the Lord;
taught how to sing them: [even] all that were cunning;
expert and well skilled in the science of singing: was two hundred and eighty eight;
for there being twenty four classes answerable to those of the priests, and twelve in each class, twelve times twenty four makes two hundred and eighty eight.

1 Chronicles 25:7 In-Context

5 God gave to Heman, the king's prophet, these fourteen sons and also three daughters, as he had promised, in order to give power to Heman.

6 All of his sons played cymbals and harps under their father's direction, to accompany the Temple worship. And Asaph, Jeduthun, and Heman were under orders from the king.

7 All these twenty-four men were experts; and their fellow Levites were trained musicians. There were 288 men in all.
