Exodus 5:7

4 And the king of Egypt said to them, Why do you, Moses and Aaron, take the people away from their work? get back to your work.

5 And Pharaoh said, Truly, the people of the land are increasing in number, and you are keeping them back from their work.

6 The same day Pharaoh gave orders to the overseers and those who were responsible for the work, saying,

7 Give these men no more dry stems for their brick-making as you have been doing; let them go and get the material for themselves.

8 But see that they make the same number of bricks as before, and no less: for they have no love for work; and so they are crying out and saying, Let us go and make an offering to our God.

9 Give the men harder work, and see that they do it; let them not give attention to false words.

10 And the overseers of the people and their responsible men went out and said to the people, Pharaoh says, I will give you no more dry stems.
