Genesis 35:2-4

2So Jacob said to his family and all who were with him, “Get rid of the foreign gods that are among you. Purify yourselves and change your clothes.

3We must get up and go to Bethel. I will build an altar there to the God who answered me in my day of distress. He has been with me everywhere I have gone.”

4Then they gave Jacob all their foreign gods and their earrings, and Jacob hid them under the oak near Shechem.
