Genesis 35:1-2, 4

Then God said to Jacob, “Go up to Bethel and settle there, and build an altar there to God, who appeared to you when you were fleeing from your brother Esau.” So Jacob said to his household and to all who were with him, “Get rid of the foreign gods you have with you, and purify yourselves and change your clothes.

So they gave Jacob all the foreign gods they had and the rings in their ears, and Jacob buried them under the oak at Shechem.
