Exodus 5:15-18

15Then the officers of the children of Israel came and cried to Pharaoh, saying, Why dost thou deal thus with thy bondmen?

16There is no straw given to thy bondmen, and they say to us, Make brick; and behold, thy bondmen are beaten, but it is the fault of thy people.

17And he said, Ye are idle, idle! therefore ye say, Let us go and sacrifice to Jehovah.

18And now go — work! and straw shall not be given you, and ye shall deliver the measure of bricks.
