Genesis 33:18-20

When Jacob came from Paddan-aram, he arrived safely and in peace at the city of Shechem, in the land of Canaan, and camped in front of the [walled] city. Then he bought the piece of land on which he had pitched his tents from the sons of Hamor, Shechem’s father, for a hundred pieces of money. There he erected an altar and called it El-Elohe-Israel.
