Bible: Exod. 4:21-23

4:21 The Lord said 1  to Moses, “When you go back to Egypt, 2  see that you 3  do before Pharaoh all the wonders I have put under your control. 4  But I will harden 5  his heart 6  and 7  he will not let the people go. 4:22 You must say 8  to Pharaoh, ‘Thus says 9  the Lord, “Israel is my son, my firstborn, 10  4:23 and I said to you, ‘Let my son go that he may serve 11  me,’ but since you have refused to let him go, 12  I will surely kill 13  your son, your firstborn!”’
