21. The Lord said to Moses, “When you return to Egypt, see that you perform before Pharaoh all the wonders I have given you the power to do. But I will harden his heart so that he will not let the people go.
22. Then say to Pharaoh, ‘This is what the Lord says: Israel is my firstborn son,
23. and I told you, “Let my son go, so he may worship me.” But you refused to let him go; so I will kill your firstborn son.’ ”
24. At a lodging place on the way, the Lord met Moses and was about to kill him.
