Genesis 35:1-3

And God said unto Jacob, Arise, go up to Beth-el, and dwell there: and make there an altar unto God, who appeared unto thee when thou fleddest from the face of Esau thy brother. Then Jacob said unto his household, and to all that were with him, Put away the foreign gods that are among you, and purify yourselves, and change your garments: and let us arise, and go up to Beth-el; and I will make there an altar unto God, who answered me in the day of my distress, and was with me in the way which I went.
