Exodus 4
21 Ref And the Lord said to Moses, When you go back to Egypt, see that you do before Pharaoh all the wonders which I have given you power to do: but I will make his heart hard and he will not let the people go.
22 Ref And you are to say to Pharaoh, The Lord says, Israel is the first of my sons:
23 Ref And I said to you, Let my son go, so that he may give me worship; and you did not let him go: so now I will put the first of your sons to death.
24 Ref Now on the journey, at the night's resting-place, the Lord came in his way and would have put him to death.
25 Ref Then Zipporah took a sharp stone, and cutting off the skin of her son's private parts, and touching his feet with it, she said, Truly you are a husband of blood to me.
26 So he let him go. Then she said, You are a husband of blood because of the circumcision.
27 Ref And the Lord said to Aaron, Go into the waste land and you will see Moses. So he went and came across Moses at the mountain of God, and gave him a kiss.
28 Ref And Moses gave Aaron an account of all the words of the Lord which he had sent him to say, and of all the signs which he had given him orders to do.
29 Ref Then Moses and Aaron went and got together all the chiefs of the children of Israel:
30 Ref And Aaron said to them all the words the Lord had said to Moses, and did the signs before all the people.
31 Ref And the people had faith in them; and hearing that the Lord had taken up the cause of the children of Israel and had seen their troubles, with bent heads they gave him worship.
