As I read through these various Bible verses about trumpets, I found there were several uses for trumpets that were specifically mentioned. Among these were the following:

• To assemble a large group of people
• To give direction to a large group of people
• To alert people to coming danger or judgment
  
• Used along with other instruments and singers to celebrate holy days and sacred events
• As a battle signal
• To make an announcement or proclamation
• As a regular part of worship ceremonies
  
• To praise God
• As God's signal to humanity

Wow -- if you made it through the reading of that whole list, you deserve some kind of award. If you also looked up and read each of the corresponding verses, you are a true scholar. This Bible study was very enlightening to me. The trumpet is a common theme in the Bible; and by studying these themes we can draw parallels and compare Scripture with Scripture. I hope you have benefited, as I have, from this look at the most frequently mentioned instrument in the Bible. Stay tuned for a (much shorter) summary of trumpet verses in the New Testament!
