Exodus 5:1-9

And afterward Moses and Aaron came, and said unto Pharaoh, Thus saith Jehovah, the God of Israel, Let my people go, that they may hold a feast unto me in the wilderness. And Pharaoh said, Who is Jehovah, that I should hearken unto his voice to let Israel go? I know not Jehovah, and moreover I will not 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 wilderness, and sacrifice unto Jehovah 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, loose the people from their works? get you unto your burdens. And Pharaoh said, Behold, the people of the land are now many, and ye make them rest from their burdens. And the same day Pharaoh commanded 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 number of the bricks, which they did make heretofore, ye shall lay upon them; ye shall not diminish aught thereof: for they are idle; therefore they cry, saying, Let us go and sacrifice to our God. Let heavier work be laid upon the men, that they may labor therein; and let them not regard lying words.
