Dophkah
Dophkah is one of the places where the Israelites camped during their exodus from Egypt. It was one of twelve campsites near Timnah which engaged in the manufacture of copper artifacts. Dophkah is mentioned in Moses' review of the stations of the Exodus in Numbers 33:12-13 but had not mentioned previously in the biblical Exodus narrative.
Copper from Timnah, along with frankincense and myrrh from Punt, and bitumen and juniper oil from Canaan was traded to Phoenicians at Elat. The traded oils were used in Egypt's mortuary trade at Karnak in return for Nubian gold shipped across the Red Sea from Elim, the port of Thebes (the capital of Egypt during the 18th dynasty).
