21 And Yahweh said to Moses, “When you go to return to Egypt, see to it that all ^athe miraculous wonders which I have put in your hand, that you do them before Pharaoh; but as for Me, ^bI will ¹harden his heart with strength so that he will not let the people go. 22 Then you shall say to Pharaoh, ‘Thus says Yahweh, “^aIsrael is My son, My firstborn. 23 So I said to you, ‘^aLet My son go that he may serve Me’; but you have refused to let him go. Behold, ^bI will kill your son, your firstborn.”’”
