Deuteronomy 7:12-13

12“Then it shall come about, because you listen to these judgments and keep and do them, that the Lord your God will keep with you the covenant and the [steadfast] lovingkindness which He swore to your fathers.

13He will love you and bless you and multiply you; He will also bless the fruit of your womb and the fruit of your land, your grain and your new wine and your [olive] oil, the offspring of your cattle and the young of your flock, in the land which He swore to your fathers to give you.
