Genesis 35:1-2, 4

God said to Jacob, “Go to the city of Bethel and live there. Make an altar to the God who appeared to you there when you were running away from your brother Esau.” So Jacob said to his family and to all who were with him, “Put away the foreign gods you have, and make yourselves clean, and change your clothes.

So they gave Jacob all the foreign gods they had, and the earrings they were wearing, and he hid them under the great tree near the town of Shechem.
