Joshua 5-7

In Joshua 6 the description of the siege and conquest of Jericho is described. I have heard the story many, many times so I wondered if there was something I had missed. There is. In verse 10 we see the command to the army to withhold the battle cry as they circled the city. So I imagined a silent army encircling the city once then leaving the shaken defenders of Jericho until the next day.
But verse 13 offered a different picture; the seven priests were playing their trumpets. They were not leading the battle cry as they marched so what were they playing? I think they were playing a song. Surely it wasn't a song just to pass the time. These were musical priests. It seems most likely that the song they were playing was a song that praised the LORD. Now if that is what the seven musical priest were playing what was the army of God doing? Singing the words. At least twice during the Exodus the people of Israel were taught a song. First it was after they had crossed the Red Sea (Exo 15). Forty years later Moses taught them another song on the East bank of the Jordan (Deut 32). So I wonder what the song might have been. Imagine the sights and sounds witnessed by the doomed residents of Jericho: Early each morning a rank of soldiers would march out from the camp of Israel. Their arrival would be announced by the singing of a magnificent army/chorus. It was a song about a God who created everything and vanquished his foes. And the song would surround the city until the army disappeared back into their camp. Only on the final day did their song change. It was punctuated with war cry: and the walls came tumbling down.
