Tim´nath-Se´rah (portion of abundance, i.e. remaining portion), a town in the mountains of Ephraim, which was assigned to Joshua, and became the place of his residence and burial (; ). In , it is called Timnath-heres (portion of the sun); but the former is probably the correct reading, since a possession thus given to Joshua after the rest of the land was distributed (), would strictly be a portion remaining. This was probably the same with the Timnah of Josephus, the head of a toparchy lying between those of Gophna and Lydda; which seems to be recognized in a place called Tibneh, lying north-west of Gophna on the Roman road to Antipatris.
