1 Chronicles 25

 So the number of them, with their brethren who were instructed in the songs of the Lord, all who were skillful, was two hundred and eighty-eight. v.7

Read chapter 25
All the sons of Asaph, Heman and Jeduthan were skillful in music.  There were 24 sons total of theirs each was a leader of eleven (twelve man group therefore) which adds up to 288 men instructed in the songs of the Lord.  The eleven under each leader were their sons and relatives, not just any Israelite.  Talk about a musical family!  Why does it seem like families are either musical or their not?  Influence by music is powerful and seems to be if the parents put priority and joy in music it reflects onto their children in various forms whether enjoying the same instruments and sounds or finding more unique ways and skills in music.  Just like the lots casts for the priests of their duties so lots were casts for the musicians and would serve for one week at a time.  Music was not just a white noise but a ministry and a task and gift from God.  It completed worship at the temple.  As Matthew Henry put it, "If the Spirit of God do not put life and fervour into our devotions, they will, however ordered, be a lifeless, worthless form."  Are you musical?  If so, what was your influence and do you use it in worship to God?  If you're not musical, how can you appreciate music in worship?
