The most valuable interpreters agree, that this Sychar is the city called Shechem; it was originally a parcel of a field bought by Jacob of Hamor, the father of Shechem, Genesis 33:19. Jeroboam built the city there, called Shechem, 1 Kings 12:25. It was in the lot of Mount Ephraim. Joseph's bones were there buried, Joshua 24:32. Jacob gave it to his son Joseph, as a parcel above his brethren, Genesis 48:22; a parcel of ground near unto which was this city called Sychar, anciently Shechem.
