Deuteronomy 7:12-14 MSG

12 And this is what will happen: When you, on your part, will obey these directives, keeping and following them, God, on his part, will keep the covenant of loyal love that he made with your ancestors:
13 He will love you, he will bless you, he will increase you.
14 You'll be blessed beyond all other peoples: no sterility or barrenness in you or your animals.
