Deuteronomy 7:12-14

And it shall come to pass, because ye hearken to these ordinances, and keep and do them, that Jehovah thy God will keep with thee the covenant and the lovingkindness which he sware unto thy fathers: and he will love thee, and bless thee, and multiply thee; he will also bless the fruit of thy body and the fruit of thy ground, thy grain and thy new wine and thine oil, the increase of thy cattle and the young of thy flock, in the land which he sware unto thy fathers to give thee. Thou shalt be blessed above all peoples: there shall not be male or female barren among you, or among your cattle.
