Beside refusing to dismiss the children of Israel, he ordered, on the very day of Moses and Aaron's audience with him, that the people be required to deliver the prescribed tale of bricks, though the taskmasters were not as heretofore to give them straw to make brick. Another decree was, that the children of Israel were not to be permitted to rest on the Sabbath, for Pharaoh knew that they used the leisure for reading the rolls that described their redemption.
All this was a part of God's plan, the oppression of Israel was to be increased the closer the end approached. As they wandered up and down the land of Egypt gathering the straw they needed for the due tale of bricks, they were maltreated by the Egyptians if they caught them on their fields. Such unkind acts perpetrated by the whole people made it impossible for them to cast the entire blame for the bondage of Israel upon Pharaoh.
All the Egyptians showed cruelty to the Israelites on their straw foraging expeditions, and therefore the Divine punishment descended upon all alike.
