Exodus 5:5-9

5:5 Pharaoh was thinking, “The people of the land are now many, and you are giving them rest from their labor.”

5:6 That same day Pharaoh commanded the slave masters and foremen who were over the people: 5:7 “You must no longer give straw to the people for making bricks as before. Let them go and collect straw for themselves. 5:8 But you must require of them the same quota of bricks that they were making before. Do not reduce it, for they are slackers. That is why they are crying, ‘Let us go sacrifice to our God.’ 5:9 Make the work harder for the men so they will keep at it and pay no attention to lying words!”

Exodus 5:18

5:18 So now, get back to work! You will not be given straw, but you must still produce your quota of bricks!”
