Exodus 5:15-18

15So the Israelite foremen went and appealed to Pharaoh: “Why are you treating your servants this way? 16No straw has been given to your servants, yet we are told, ‘Make bricks!’ Look, your servants are being beaten, but the fault is with your own people.”

17“You are slackers!” Pharaoh replied. “Slackers! That is why you keep saying, ‘Let us go and sacrifice to the LORD.’ 18Now get to work. You will be given no straw, yet you must deliver the full quota of bricks.”
