The Lord will bring prosperity in all the Israelites do: in their families, crops, and land. He will remove sickness and conquer those who had lived in this land and the Israelites shall be as numerous as the stars, but only if they obey. (Deuteronomy 7:12-24)f

If the Israelites follow the Lord's instructions then He will bestow blessing as which he has promised before, such as making the people as numerous as the stars above, the mass production and fertility of crops, the land which God has given them, the conquering of the pagans. He will remove sickness from the people and replace it with long lasting health. These are the blessings that are rewarded only if the Israelites are obedient.
