And Jacob came in peace to the town of Shechem…And he bought a portion of the field where he had pitched his tent…And he set up an altar there…Some suggest that before building an altar, Jacob wished to own the land so nobody could interfere with his worship. Others suggest that he wanted to demonstrate that now he was back and settling in Canaan permanently. Ibn Ezra suggests that Jacob did not buy the very land on which he pitched his tent. He writes that Scripture is informing us of the greatness of owning a portion of the promised land – for this is akin to possessing a portion in olam ha-ba, the world to come.
