Genesis 33:18-20

And Jacob came to Shalem, a city of Shechem, which is in the land of Canaan, when he came from Padan-aram; and pitched his tent before the city. And he bought a parcel of a field, where he had spread his tent, at the hand of the children of Hamor, Shechem's father, for an hundred pieces of money. And he erected there an altar, and called it El-elohe-Israel.
