Moses took the bones of Joseph with him because Joseph had made the sons of Israel swear an oath. He had said, "God will surely come to your aid, and then you must carry my bones up with you from this place." (Exo 13:19)For a thousand years, Jews had prayed at and cared for the Tomb of the Patriarch Joseph. The Samaritans had worshipped at the Tomb for 1,700 years.
On October 7, 2000, Ehud Barak ordered Israeli Border Police to withdraw from guarding the Tomb in the West Bank city of Nablus (Shechem). Within hours it was destroyed. Since then there has been a pattern of the IDF escorting religious Jews to clean up the destruction, and then more desecration after they leave.
The bones of Joseph which the Children of Israel brought up from Egypt were buried in Shechem in the portion of the field that had been purchased by Jacob. (Joshua 24:32)
