Joshua 24:30

‘ And they buried him in the border of his inheritance, in Timnath-serah, which is in the hill country of Ephraim, on the north of the mountain of Gaash.'

Joshua was buried in a burial place outside the city which was his inheritance, Timnath-serah (Joshua 19:50). It is possibly Khirbet Tibneh, twenty seven kilometres (seventeen miles) south west of Shechem, which lies on the south side of a deep ravine, which must then be the mountain of Gaash. It was in the hill country of Ephraim. The Wadis of Gaash are mentioned in 2 Samuel 23:30 which would possibly be connected in some way with the mountain.
