Joshua 19:50 - Albert Barnes' Notes on the Bible

Nothing is said of any express command of God respecting the inheritance of Joshua. But as such special portion appears to have been promised to Caleb at the time when he and Joshua alone out of the twelve spies remained faithful Joshua 14:6-9, it is probable that a like promise was made to Joshua. The name of the place is also written Timnath-heres Judges 2:9, by a transposition of the letters. The rabbinical explanation that the name Timnath-heres (i. e. “portion of the sun”) was given because a representation of the sun was affixed to the tomb in memory of Joshua’s command to the sun to stand still, appears to be an afterthought. The name Timnath-serah (“portion that remains”) was perhaps conferred on the spot in consequence of its being allotted to Joshua, the last allotment made in the whole distribution of his conquests. The site has been conjectured to be “Tibneh,” a village about five miles north-west of Lydda (or, by Conder, Kerr Hares, nine miles south of Nablous).
