TSK · Exodus 32:3

He restored the eleven hundred [pieces] of silver to his mother; and his mother said, "I most certainly dedicate the silver to Yahweh from my hand for my son, to make an engraved image and a molten image. Now therefore I will restore it to you."

A workman has cast an image, and the goldsmith overlays it with gold, and casts silver chains for it.

There is silver beaten into plates, which is brought from Tarshish, and gold from Uphaz, the work of the artificer and of the hands of the goldsmith; blue and purple for their clothing; they are all the work of skillful men.
