Why Did Solomon want it quiet when the Temple was built.  No Sound of the hammer.

Genesis 4:20-22 I Chronicles 22:8
Exodus 20:25 I Chronicles 28:3
Deuteronomy 27:5 I Kings 8:18-19
Joshua 8:31  

Could it be that the hammer was associated with violence back to Cain.  It was one of Cain's decedents who was the first metallurgist?
