So that we worship God, not images made by man.The two accounts have key differences. For the former, the Holy Spirit inspired for our profit explicit revelation that concerned the sound of the composite sound emanating from the camp that was heard by Joshua and Moses at a distance from the camp:
Exod. 32:17 And when Joshua heard the noise of the people as they shouted, he said unto Moses, There is a noise of war in the camp.
18 And he said, It is not the voice of them that shout for mastery, neither is it the voice of them that cry for being overcome: but the noise of them that sing do I hear.
Why did the Spirit want us to know this information? Why is it in Scripture? How are we supposed to profit from it?
Again, provide regulations against types of music or admit you have none and you are merely bringing up your own preference of music.
