Exodus 5:11 Go, get yourselves straw where you can find it; yet none of your work will be reduced.
Pharaoh did not want to allow the Hebrews to go; they were the servants who worked the best!
When Moses and Aaron came to Pharaoh to ask him to let the people go he turned things round and made their work even harder than it was before.
Moses was trying to follow God’s wishes and even told Pharaoh what those wishes were.
Pharaoh had to learn the hard way that coming up against God was not the best plan he had!
