Deuteronomy 28:8-9

Jehovah will command the blessing upon thee in thy barns, and in all that thou puttest thy hand unto; and he will bless thee in the land which Jehovah thy God giveth thee. Jehovah will establish thee for a holy people unto himself, as he hath sworn unto thee; if thou shalt keep the commandments of Jehovah thy God, and walk in his ways.
