Genesis 35:2-4

2Then Jacob said to his household, and to all that were with him, Put away the foreign gods that are among you, and be clean, and change your garments:

3And let us arise, and go up to Bethel; and I will make there an altar to God, who answered me in the day of my distress, and was with me in the way which I went.

4And they gave to Jacob all the foreign gods which were in their hand, and the earrings which were in their ears; and Jacob hid them under the oak which was by Shechem.
