Genesis 35:2-4

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. Then come, let us go up to Bethel, where I will build an altar to God, who answered me in the day of my distress and who has been with me wherever I have gone.” 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.
