 Moses descends from the mountain forty days later with the Sefer Torah he wrote, and with two rectangular lapis lazuli tablets, into which Yahweh had carved the Ten Commandments in Paleo–Hebrew.In his absence, Aaron has constructed an image of Yahweh, depicting him as a young golden calf, and has presented it to the Israelites, declaring "Behold O Israel, this is your god who brought you out of the land of Egypt".Moses smashes the two tablets and grinds the golden calf into dust, then throws the dust into a stream of water flowing out of Mount Sinai, and forces the Israelites to drink from it.
