From the desert and from Libanus unto the great river Euphrates, all the land of the Hethites unto the great sea toward the going; down of the sun, shall be your border.

“From the wilderness and this Lebanon. The wilderness refers to the wilderness of Kodeish, the wilderness of Tzin, which was adjacient to Edom which was to the south east, the direction from which they entered the land, as it is said: And behold we are in Kodeish. How do we know that it was southeast? It is said: ‘Your southern flank will be from the Tzin wilderness along Edom.’ To the great river, the Euphrates river. This refers to its width from south to north. This includes all the land of the Chitim. To the Great Sea [westward]. This refers to its length from east to west.”

“From the wilderness,.... The wilderness of Kadesh and Sin, on the border of Edom; in the southeast corner, as Jarchi says, see Num 34:3, and this Lebanon; which though on the other side Jordan, and at a considerable distance, being the northern border of the land towards Syria, might be seen afar off; or it is expressed, because it was a well known place, as Kimchi remarks: even unto the great river, the river Euphrates; which was the eastern border of the land, and to which it reached in the times of Solomon, whose dominion extended thither, Kg1 4:21; according to Jarchi, this was its breadth from south to north: all the land of the Hittites: who, though only one of the seven nations of Canaan, are put for the rest, and the rather mentioned, because, as their name signifies, they were very formidable and terrible; among them dwelt the Anakim, and they themselves were very warlike and populous; or they are taken notice of particularly here, because they dwelt in the western part of the land described by them, so Kimchi thinks; according to Jarchi, this was its length from east to west: and unto the great sea: the Mediterranean sea, which was the western border of the land of Canaan, called great, in comparison of the sea of Tiberias, and the salt sea, which were in it: toward the going down of the sun, shall be your coast; the western coast; see Gill on Deu 11:24; this will be more fully verified in Christ, when his kingdom is from sea to sea, Psa 72:8.”

“From the wilderness and this Lebanon - Joshua appears to be standing with his face towards the promised land, and pointing out the different places, or their situation, with his hand, This Lebanon, etc. The utmost of their limits should be from the desert of Arabia Petraea on the South to Lebanon on the North: and from the Euphrates on the East to the Mediterranean Sea on the West. The Israelites did not possess the full extent of this grant till the days of David. See Sa2 8:3, etc., and Ch2 9:26. Land of the Hittites - These are generally reputed to have been the most hardy and warlike of all the Canaanitish nations; and as they occupied the mountainous countries on the south of the land of Canaan, it is natural to suppose that they would be the most difficult to subdue, and on this account, it is supposed, God particularly specifies these: "Ye shall subdue and possess even all the land of the Hittites," but it is probable that under this one term all the other nations are included, as it is certain they are in other places under the term Amorites. Great sea: The Mediterranean, called great in respect of the lakes in the land of Judea, such as the sea of Gennesareth, or the sea of Tiberias, and the Dead Sea, which were comparatively small lakes; but the Hebrews gave the name of sea, ים yam, to every large collection of waters.”

“all the land of the Hittites--These occupied the southern extremities and were the dominant tribe of Canaan. Their superior power and the extent of their dominions are attested by the mention of them under the name of Khita, on the Assyrian inscriptions, and still more frequently on the Egyptian inscriptions of the eighteenth and nineteenth Dynasties. What life and encouragement must have been imparted to Joshua by the assurance that his people, who had been overwhelmed with fear of that gigantic race, were to possess "all the land of the Hittites"!”

“The boundaries of the land are given as in Deu 11:24, with the simple difference in form, that the boundary line from the desert (of Arabia) and Lebanon, i.e., from the southern and northern extremity, is drawn first of all towards the east to the great river, the Euphrates, and then towards the west to "the great sea, toward the going down of the sun," i.e., the Mediterranean; and then between these two termini ad quem the more precise definition is inserted, "all the land of the Hittites;" whereas in Deuteronomy the southern, northern, and eastern boundaries are placed in antithesis to the western boundary, and the more precise definition of the country to be taken is given by an enumeration of the different tribes that were to be destroyed by the Israelites (Deu 11:23). On the oratorical character of these descriptions, see at Gen 15:18. The demonstrative pronoun "this," in connection with Lebanon, may be explained from the fact that Lebanon, or at all events Anti-libanus, was visible from the Israelitish camp. The expression "the Hittites" (see at Gen 10:15) is used here in a broader sense for Canaanites in general, as in Kg1 10:29; Kg2 7:6; Eze 16:3. The promise in Jos 1:5 is adopted from Deu 11:25, where it was made to the whole nation, and specially transferred to Joshua; and Jos 1:5 is repeated from Deu 31:8, as compared with Jos 1:6.”
