Genesis 35:2-4

2Then Jacob said to his household and to all who were with him, “Get rid of the [idols and images of] foreign gods that are among you, and ceremonially purify yourselves and change [into fresh] clothes;

3then let us get up and go up to Bethel, and I will make an altar there to God, who answered me in the day of my distress and has been with me wherever I have gone.”

4So they gave Jacob all the [idols and images of the] foreign gods they had and the rings which were in their ears [worn as charms against evil], and Jacob buried them under the oak tree near Shechem.
