Exodus 5:5-9

5And Pharaoh said, Behold the people of the land are now many, and ye wish to make them rest from their burdens.

6And Pharaoh commanded the same day the taskmasters of the people, and their officers, saying,

7Ye shall no more give the people straw to make brick, as heretofore: let them go and gather straw for themselves.

8And the number of the bricks they have made heretofore shall ye lay upon them: ye shall not diminish any of it, for they are idle; therefore they cry, saying, Let us go [and] sacrifice to our 1God.

9Let them put heavier labour on the men, that they may be taken up with it, and not regard vain words.
