Exodus Chapter 5 Verse 1And afterward Moses and Aaron went in, and told Pharaoh, Thus saith the LORD God of Israel, Let my people go, that they may hold a feast unto me in the wilderness.

And thou shalt say unto Pharaoh, Thus saith the LORD, Israel [is] my son, [even] my firstborn:

And I say unto thee, Let my son go, that he may serve me: and if thou refuse to let him go, behold, I will slay thy son, [even] thy firstborn.

And it came to pass by the way in the inn, that the LORD met him, and sought to kill him.

Then Zipporah took a sharp stone, and cut off the foreskin of her son, and cast [it] at his feet, and said, Surely a bloody husband [art] thou to me.

So he let him go: then she said, A bloody husband [thou art], because of the circumcision.

And the LORD said to Aaron, Go into the wilderness to meet Moses. And he went, and met him in the mount of God, and kissed him.

And Moses told Aaron all the words of the LORD who had sent him, and all the signs which he had commanded him.

And Moses and Aaron went and gathered together all the elders of the children of Israel:

And Aaron spake all the words which the LORD had spoken unto Moses, and did the signs in the sight of the people.

And the people believed: and when they heard that the LORD had visited the children of Israel, and that he had looked upon their affliction, then they bowed their heads and worshipped.

And Pharaoh said, Who [is] the LORD, that I should obey his voice to let Israel go? I know not the LORD, neither will I let Israel go.

And they said, The God of the Hebrews hath met with us: let us go, we pray thee, three days' journey into the desert, and sacrifice unto the LORD our God; lest he fall upon us with pestilence, or with the sword.

And the king of Egypt said unto them, Wherefore do ye, Moses and Aaron, let the people from their works? get you unto your burdens.

And Pharaoh said, Behold, the people of the land now [are] many, and ye make them rest from their burdens.

And Pharaoh commanded the same day the taskmasters of the people, and their officers, saying,

Ye shall no more give the people straw to make brick, as heretofore: let them go and gather straw for themselves.

And the tale of the bricks, which they did make heretofore, ye shall lay upon them; ye shall not diminish [ought] thereof: for they [be] idle; therefore they cry, saying, Let us go [and] sacrifice to our God.

Let there more work be laid upon the men, that they may labour therein; and let them not regard vain words.

And the taskmasters of the people went out, and their officers, and they spake to the people, saying, Thus saith Pharaoh, I will not give you straw.

Go ye, get you straw where ye can find it: yet not ought of your work shall be diminished.
