'Strange' in the Bible

Then 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;

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.
