Horses, and chariots - The most formidable elements of an Oriental host, which the Canaanites possessed in great numbers; compare Joshua 17:16; Jdg 4:3; 1 Samuel 13:5. Israel could not match these with corresponding forces (compare Deuteronomy 17:16 note and references), but, having the God of battles on its side, was not to be dismayed by them; the assumption being that the war had the sanction of God, and was consequently just.
