Moses pleaded that the Israelites will be let go and freed from slaverly but the Pharaoh shouted,'NO!'.
'Then you shall face the wrath of God!' Moses exclaimed as he left the greedy Pharaoh.
Moses went to the Isralites and explained his conversation with the Pharaoh.'But never fear friends for if you put lambs blood over your door no harm shall come your way,' Moses reassured.
Then the wrath of God came and with it nine plagues.
Each time a plague started the Pharaoh would free the slaves only to make them slaves again as soon as a plague stopped.This cycle happened until the last one where all slaves where let go but leaving the city in ruins.
The Pharaoh was left alone in his ruined city and weeped for days.
