When thou goest out to battle against thine enemies, and seest horses, and chariots, and a people more than thou, be not afraid of them: for the LORD thy God is with thee, which brought thee up out of the land of Egypt. When thou goest out to battle - This refers chiefly to the battles they were to have with the Canaanites, in order to get possession of the promised land; for it cannot be considered to apply to any wars which they might have with the surrounding nations for political reasons, as the Divine assistance could not be expected in wars which were not undertaken by the Divine command.
