Deuteronomy 7:12-13

12“Then it will happen, as a result of your listening to these ordinances, when you keep and do them, that Adonai your God will keep with you the covenant kindness that He swore to your fathers.

13He will love you, bless you and multiply you. He will also bless the fruit of your womb and the produce of your soil, your grain and your new wine and your oil, the increase of your herds and the young of your flock, in the land that He swore to your fathers to give you.
