Joshua 17:16

The hill is not enough for us - The mountain of Gilboa being that which had fallen to them by lot.

Chariots of iron - We cannot possess the plain country, because that is occupied by the Canaanites; and we cannot conquer them, because they have chariots of iron, that is, very strong chariots, and armed with scythes, as is generally supposed.

The possession by the Canaanites of chariots strengthened and tipped with iron, such as were used by the Egyptians Exodus 14:7, is named here by the children of Joseph as a reason why they could not possess themselves of the plains. "The valley of Jezreel" is the broad low valley which sweeps from "Zerin" between the mountains of Gilboa and the range of little Hermon eastward down to the Jordan. It was most likely in this valley that the host of the Midianites was encamped, when attacked by Gideon Judges 7:1, Judges 7:8. The great plain of Jezreel, called the plain of Esdraelon (Esdrelom, Judith 1:8), extends from Carmel on the west to the hills of Gilboa, little Hermon, and Tabor on the east, a distance of full sixteen miles; and its breadth between the rocky mass of southern Palestine and the bolder mountains of Galilee on the north, is about twelve miles. Its position as well as its open area make it the natural battlefield of Palestine.

17:16 Is not enough - Heb. the hill will not be found, that is, obtained by us; those fierce and strong people the Perizzites and the giants will easily defend themselves, and frustrate our attempts, having the advantage of the woods and mountains. The Canaanites that dwell - That is, and if thou sayest, that if the hill either cannot be conquered, or is not sufficient for us, we may go down and take more land out of the pleasant and fruitful valleys, we shall meet with no less difficulty there than in the mountains. Chariots of iron - Not all made of iron, but armed with iron, not only for defence, but for offence also, having as it were scythes and swords fastened to them, to cut down all that stood in their way.
