 This was an area which had many Jewish memories attached to it. There was a piece of ground there which had been bought by Jacob ( Genesis 33:18-19). Jacob, on his deathbed, had bequeathed that ground to Joseph ( Genesis 48:22). And, on Joseph's death in Egypt, his body had been taken back to Palestine and buried there ( Joshua 24:32). So around this area there gathered many Jewish memories.
