Exodus 5:9

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

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

8 And the number of the bricks, which they did make heretofore, ye shall lay upon them; ye shall not diminish aught thereof: for they are idle; therefore they cry, saying, Let us go and sacrifice to our God.

9 Let heavier work be laid upon the men, that they may labor therein; and let them not regard lying words.

10 And the taskmasters of the people went out, and their officers, and they spake to the people, saying, Thus saith Pharaoh, I will not give you straw.

11 Go yourselves, get you straw where ye can find it: for nought of your work shall be diminished.

12 So the people were scattered abroad throughout all the land of Egypt to gather stubble for straw.
