Exodus 4:21-23

English Standard Version

²¹ And the Lord said to Moses, “When you go back to Egypt, see that you do before Pharaoh all the ^(A)miracles that I have put in your power. But ^(B)I will harden his heart, so that he will not let the people go. ²² Then you shall say to Pharaoh, ‘Thus says the Lord, ^(C)Israel is my ^(D)firstborn son, ²³ and I say to you, “Let my son go that he may serve me.” If you refuse to let him go, behold, I ^(E)will kill your firstborn son.’”
