Tahtim-hodshi - Where this place was is not exactly known: some think that the words refer to a newly conquered country, as our margin, the nether land newly inhabited; and if so, this was probably the country eastward of Gilead, which the Israelites, in the time of Saul, had conquered from the Hagarites, and dwelt in themselves. See Ch1 5:10, where this transaction is recorded.
To Dan-jaan - Or, to Dan of the woods. This is the place so frequently mentioned, situated at the foot of Mount Libanus, near to the source of the Jordan, the most northern city of all the possessions of the Israelites in what was called the promised land, as Beer-sheba was the most southern: hence the common form of speech, From Dan to Beer-sheba, i.e., from north to south.

and they came to Danjaan; the same that is simply called Dan, and formerly Leshem, Jos 19:47; why Juan is added to it is not easy to say; it lay at the northern border of the land of Israel, and was four miles from Paneas as you go to Tyre (x):

and about to Zidon; from Dan they went round about to Zidon, to the parts adjacent to it; for with Zidon itself they had nothing to do, of which See Gill on Jos 11:8.

the land of Tahtim-hodshi--that is, the land lately acquired; namely, that of the Hagarites conquered by Saul (Ch1 5:10). The progress was northward. Thence they crossed the country, and, proceeding along the western coast to the southern extremities of the country, they at length arrived in Jerusalem, having completed the enumeration of the whole kingdom in the space of nine months and twenty days.
