Genesis 35:1-3

God spoke to Jacob: “Go back to Bethel. Stay there and build an altar to the God who revealed himself to you when you were running for your life from your brother Esau.” Jacob told his family and all those who lived with him, “Throw out all the alien gods which you have, take a good bath and put on clean clothes, we’re going to Bethel. I’m going to build an altar there to the God who answered me when I was in trouble and has stuck with me everywhere I’ve gone since.”
