Brothers and Sisters,
33 Those who were musicians, heads of Levite families, stayed in the rooms of the temple and were exempt from other duties because they were responsible for the work day and night. (1 Chronicles 9)
What was the work the musicians appointed to perform day and night? Their work was continuous praise of the Lord in the temple. Some people wrongly think that praising God depends on their mood; it all depends on their feeling. But, a very important and necessary task cannot be left to feeling alone, there needs to be a sense of duty, otherwise the task could be neglected in difficult time. David said, "I will bless the Lord at all times;: his praise shall continually be in my mouth" (Psalm 34:1). Since there is unceasing praise in heaven (Revelation 4:8), it is necessary to have continuous praise on earth as well.
Please read 1 Chronicles 8 - 10. And Listen.
May the Lord richly bless you!
