The portion discusses the counting of the Israelites, the washbasin of the Tabernacle, the anointing oils for the priests and kings, the incense offering, and the Sabbath. The Torah then relates the story of the Golden Calf, G‑d's anger at the Jewish people, Moses successfully arguing for Divine forgiveness for the sin, the subsequent breaking of the tablets, and the giving of the second tablets.
