Genesis 35:2-4

So Jacob said to his household and to all who were with him, “Put away the foreign gods which are among you, and purify yourselves and change your garments; and let us arise and go up to Bethel, and I will make an altar there to God, who answered me in the day of my distress and has been with me wherever I have gone.” So they gave to Jacob all the foreign gods which they had and the rings which were in their ears, and Jacob hid them under the oak which was near Shechem.
