Adam Clarke Bible Commentary

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.
