Genesis 35:2-4

2So Jacob told the people in his house and everyone who was with him, ‘Throw out all the foreign idols that you have with you. Wash your body very well and put on clean clothes.

3Then we will go to Bethel. I will build an altar there to worship God. He is the one who answered me when I was in trouble. And he has been with me everywhere that I went.’

4So the people gave to Jacob all their idols and the rings that were in their ears. Jacob buried these things under the oak tree near Shechem city.
