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 (All of them were the sons of the king's seer Heman. They were given to him to make him prominent, as God had promised. So God gave Heman 14 sons and 3 daughters.)

6 All these [Levites] sang at the LORD's temple under the direction of their fathers Asaph, Jeduthun, and Heman. They played cymbals, lyres, and harps for worship in God's temple under the direction of the king.

7 They, along with their relatives, were trained, skilled musicians for the LORD. There were 288 of them.

8 They drew lots for their assignment of duties, the youngest as well as the oldest, the skilled [musicians] along with the students.

9 The first lot drawn chose Joseph, the son of Asaph. The second chose Gedaliah, his sons, and his relatives--12 men.
