This spelling is suspect, since its existence is otherwise unattested, and the parallel passage in Joshua 24:30 has Timnath-serah
(see also Joshua 19:50). It’s possible that Timnath-heres
is an alternative name for the location, or a scribal error.1
9 And they buried him within the boundaries of his inheritance in Timnath-heres, in the hill country of Ephraim, north of the mountain of Gaash.
