until Yahweh have given your brothers rest, as [he has given] you, and they also have possessed the land which Yahweh your God gives them: then you shall return to the land of your possession, and possess it, which Moses the servant of Yahweh gave you beyond the Jordan toward the sunrise.
Now God is saying, "Look keep the law, don't deviate from it, for it is by this observing it day and night, meditating in it, thus thou shalt make thy way prosperous, thus you will have good success."
