And you shall make two cherubim of gold; of hammered work shall you make them, on the two ends of the mercy seat.
#exodus 25:18

The Ark of the Covenant, the Menorah, and the Shewbread Table were made of beaten, not molded gold. A pure heart comes through long struggle. Life's scars are necessary, but temporary. Beating out the gold, like beating out the righteous character of a faithful child of YHVH, was a violent process, but it was also carefully planned and executed.
