Thimnathah - Probably the same as Timnah. See on Joshua 15:57 (note).

Ekron - A well-known city of the Philistines and the metropolis of one of their five dynasties.

And Elon,.... Of Elon no mention is made elsewhere:

and Thimnathah is a different place from Timnah in the tribe of Judah, Joshua 15:10. Jerom (s) speaks of the Thamnitic country, so called from the village Thamna, which seems to be this:

and Ekron was one of the five principalities of the Philistines, and never possessed by the Israelites; it first fell by lot to the tribe of Judah, and afterwards given to the tribe of Dan, Joshua 15:45.

(s) De loc. Heb. fol. 88. E.

Elon, which is mentioned again in 1 Kings 4:9, with the addition of Beth-hanan, has not yet been traced; according to Knobel, it "may possibly be Ellin, near Timnath and Beth-shemesh, mentioned by Robinson in his Pal. vol. iii. App." Thimna (Thimnathah) and Ekron, on the boundary of Judah (see at Joshua 15:10-11).

And Elon, and Thimnathah, and Ekron,

19:17-51 Joshua waited till all the tribes were settled, before he asked any provision for himself. He was content to be unfixed, till he saw them all placed, and herein is an example to all in public places, to prefer the common welfare before private advantage. Those who labour most to do good to others, seek an inheritance in the Canaan above: but it will be soon enough to enter thereon, when they have done all the service to their brethren of which they are capable. Nor can any thing more effectually assure them of their title to it, than endeavouring to bring others to desire, to seek, and to obtain it. Our Lord Jesus came and dwelt on earth, not in pomp but poverty, providing rest for man, yet himself not having where to lay his head; for Christ pleased not himself. Nor would he enter upon his inheritance, till by his obedience to death he secured the eternal inheritance for all his people; nor will he account his own glory completed, till every ransomed sinner is put in possession of his heavenly rest.
