Exodus 5:9-11

9Let the labor be heavier on the men, and have them work at it so that they will pay no attention to false words.”

10So 1the taskmasters of the people and their foremen went out and spoke to the people, saying, “This is what Pharaoh says: ‘I am not going to give you any straw. 11You go, get straw for yourselves wherever you can find it; but none of your labor will be reduced.’”
