Genesis 35:2,4 NASB
2So Jacob said to his household and to all who were with him, "Put away the foreign gods which are among you, and purify yourselves and change your garments; ...
4So they gave to Jacob all the foreign gods which they had and the rings which were in their ears, and Jacob hid them under the oak which was near Shechem.
There is no mention of worship of foreign gods in Jacobs family in the previous chapters other than Rachel stealing her father's gods (Genesis 31:19).
After disputing with Laban (Genesis 31:36), Jacob tells his household to bring forward all foreign gods.
Did Jacob suspect that Laban must have been telling the truth?
Are the idols brought forward the ones stolen from Laban?
Could the issue of idols have brought about the seemingly untimely death of Rachel?
