Deuteronomy 7:13

And he will love thee
As he has done, and rest in his love, and give further instances and proofs of it:

and bless thee, and multiply thee;
that is bless thee with a multiplication of offspring, which was what was often promised to Abraham, Isaac, and Jacob; that their seed should be as the stars of heaven, the dust of the earth, and the sand of the sea:

he will also bless the fruit of thy womb;
not only give strength to conceive, but carry on the pregnancy, preserve the foetus, and prevent miscarrying:

and the fruit of thy land, thy corn, and thy wine, and thine oil;
which were the principal produce of it:

the increase of thy kine, and the flocks of thy sheep:
their larger and lesser cattle, oxen and sheep: in the land which he sware unto thy fathers to give thee; the land of Canaan, given in promise, and that established by an oath.
