Exodus 5:4-8

But the king of Egypt said to them, “Moses and Aaron, why do you let the people neglect their work? Get back to your labors!”

Again Pharaoh said, “Look, the people of the land are now many, and you would have them cease from their labors!”

So the same day Pharaoh commanded the taskmasters over the people and their foremen, saying,

“You are no longer to give the people straw to make bricks as previously; have them go and gather straw for themselves.

But you shall impose on them the quota of bricks which they were making before; you are not to reduce any of it. Because they are lazy, for that reason they cry out, ‘Let us go and sacrifice to our God.’
