Joseph's burial
Joseph lived to the age of 110, living to see his great-grandchildren. Before he died, he made the children of Israel swear that when they left the land of Egypt they would take his bones with them, and on his death his body was embalmed and placed in a coffin in Egypt. (Genesis 50:22-26)
The children of Israel remembered their oath, and when they left Egypt during the Exodus, Moses took Joseph's bones with him. (Exodus 13:19) The bones were buried at Shechem, in the parcel of ground which Jacob bought from the sons of Hamor (Joshua 24:32), which has traditionally been identified with site of Joseph's Tomb, before Jacob and all his family moved to Egypt. Shechem was in the land which was allocated by Joshua to the Tribe of Ephraim, one of the tribes of the House of Joseph, after the conquest of Canaan.
This find was in "an archaeological mound in the Jezreel Valley" which would be too far north.................
