‘ For Yahweh your God will bless you, as he promised you, and you shall lend to many nations, but you shall not borrow, and you shall rule over many nations, but they shall not rule over you.'
Indeed if they were truly faithful to Him and His covenant, and laid up their tithes as Yahweh decreed, Yahweh would so bless them that as a nation they would never need to borrow, while at the same time having so much in abundance that they would be in a position to lend to other nations. They would store up abundance of wealth for themselves. They would be creditors not debtors. Furthermore because of their wealth they would rule over many nations, for wealth brings power, but none would ever rule over them. This was the glittering future promised under the kingly rule of Yahweh that would follow true response and obedience.
Such statements could only have been made by someone looking forward to such a glorious future as a possible reality in response to obedience. It would have required cynicism indeed for someone to have made them once the land had sunk into its later low level existence, with a miserable record behind it, a cynicism that could never have produced the book of Deuteronomy with its strong morality, its vibrancy and its glorious awareness of Yahweh. And there is no suggestion here that it will arise from Yahweh's cataclysmic intervention. This is in contrast with the later prophets. It positively demands that Moses is speaking prior to entry into the land.
