Genesis 35:4-5

So 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. As they journeyed, there was a great [supernatural] terror [sent from God] on the cities around them, and [for that reason] the Canaanites did not pursue the sons of Jacob.
