²¹ Again the Lord said to Moses, “Now that you are going back to Egypt, be sure to perform before the king all the miracles which I have given you the power to do. But I will make the king stubborn, and he will not let the people go. ²² Then you must tell him that I, the Lord, say, ‘Israel is my first-born son. ^23 (A)I told you to let my son go, so that he might worship me, but you refused. Now I am going to kill your first-born son.’”
