Usage of 'Raqa'
ÒTo whom, then, will you compare God?  What image will you compare him to?  As for an idol, a craftsman casts it, and a goldsmith overlays it with gold and fashions silver chains for it.Ó  Isaiah 40:19
Here raqa is applied to spreading gold leaf over a cast image, which is a rather more delicate operation than beating or stamping!
