The lot of Asher lay upon the coast of the great sea. We read not of any famous person of this tribe but Anna the prophetess, who was a constant resident in the temple at the time of our Saviour's birth, Luk 2:36. Nor were there many famous places in this tribe. Aphek (mentioned Jos 19:30) was the place near which Benhadad was beaten by Ahad, Kg1 20:30. But close adjoining to this tribe were the celebrated sea-port towns of Tyre and Sidon, which we read so much of. Tyre is called here that strong city (Jos 19:29), but Bishop Patrick thinks it was not the same Tyre that we read of afterwards, for that was built on an island; this old strong city was on the continent. And it is conjectured by some that into these two strong-holds, Sidon and Tzor, or Tyre, many of the people of Canaan fled and took shelter when Joshua invaded them.

The strong city Tyre - I suspect this to be an improper translation. Perhaps the words of the original should be retained: And the coast turneth to Ramah and to the city, מבצר צר mibtsar tsor. Our translators have here left the Hebrew, and followed the Septuagint and Vulgate, a fault of which they are sometimes guilty. The former render the place ἑως πολεως οχυρωματος των Τυριων, unto the fortified city of the Tyrians. The Vulgate is nearly the same: ad civitatem munitissimam Tyrum, to the well-fortified city Tyre; but this must be incorrect for the famous city of Tyre was not known till about A.M. 2760, about two hundred years after the days of Joshua. Homer, who frequently mentions Sidon and the Sidonians, never mentions Tyre; a proof that this afterwards very eminent city was not then known. Homer is allowed by some to have flourished in the time of Joshua, though others make him contemporary with the Israelitish judges. The word צר Tsor or Tsar, which we translate or change into Tyre, signifies a rock or strong place; and as there were many rocks in the land of Judea, that with a little art were formed into strong places of defense, hence several places might have the name of Tsar or Tyre. The ancient and celebrated Tyre, so much spoken of both in sacred and profane history, was a rock or small island in the sea, about six or seven hundred paces from the main land. In order to reduce this city, Alexander the Great was obliged to fill up the channel between it and the main land, and after all took it with much difficulty. It is generally supposed that a town on the main land, opposite to this fortified rock, went by the same name; one being called old Tyre, the other, new Tyre: it was out of the ruins of the old Tyre, or that which was situated on the main land, that Alexander is said to have filled up the channel between it and the new city. Of this city Isaiah, Isaiah 23:1-18, and Ezekiel, Ezekiel 27:1-28:26, have given a very grand description, and also predicted its irreparable ruin which prophecies have been most literally fulfilled. See more on the above places.
Achzib - Called afterwards Ecdippe, and now called Zib; it is about nine miles' distance from Ptolemais, towards Tyre.

Ummah also,.... Ummah is not mentioned any where else:

and Aphek; of which; see Gill on Jos 12:18,

and Rehob; of which; see Gill on Jos 19:28,

twenty and two cities with their villages: there are more set down in the account, but some of them did not belong to the tribe, only were on the border of it.

and then the coast turneth to Ramah--now El-Hamra, which stood where the Leontes (Litany) ends its southern course and flows westward.

and to the strong city Tyre--The original city appears to have stood on the mainland, and was well-fortified. From Tyre the boundary ran to Hosah, an inland town; and then, passing the unconquered district of Achzib (Jdg 1:31), terminated at the seacoast.
