21 And Jehovah went on to say to Moses: “After you have gone and returned to Egypt see that YOU men actually perform all the miracles that I have put in your hand before Pharʹaoh.+ As for me, I shall let his heart become obstinate;*+ and he will not send the people away.+

15 When Pharʹaoh got to see that relief had taken place, he made his heart unresponsive;*+ and he did not listen to them, just as Jehovah had spoken.+

12 But Jehovah let Pharʹaoh’s heart become obstinate, and he did not listen to them, just as Jehovah had stated to Moses.+

18 So, then, upon whom he wishes he has mercy,+ but whom he wishes he lets become obstinate.+
