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.
