Genesis 35:23

And God said unto Jacob, Arise, go up to Beth-el, and dwell there: and make there an altar unto God, that 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 strange gods that are among you, and be clean, 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.

And they gave unto Jacob all the strange gods which were in their hand, and all their earrings which were in their ears; and Jacob hid them under the oak which was by Shechem.
