First, Paroh decreed that the Jews be enslaved and taxed.
Then he decreed all birthing women be checked. If there is a boy she is about to give birth to - he should be killed. A girl - she may live.
Then he said that they must throw all baby boys in the river.
Then when he saw that everything wasn't working - he instituted the killer. He decreed that everyone must stay locked up in their homes, men, women and children. All schools must be closed. Anyone found too far away from their home will be fined. [Only the Egyptians were allowed to congregate in large numbers for their purposes - like to protest that sheeps lives matter]. This way - they will not be able to work and will eventually die of hunger. The children will stay home, not receive a Jewish education and go off the derech and often out of their minds [back then they didn't have Facebook and Instagram to keep people stimulated all day. Mark, Sheryl and the chevre - where were you when we needed you???!!!]. It will also lead to depression, anxiety, suicide and countless other problems. He explained it by saying that there is a plague [he called it a "pandemic"] and such measures are necessary for everyone's well being. Thousands of scientists disputed this assertion and signed a petition against the new decree. It didn't matter. Paroh didn't listen.
In the end - Hashem saved us.
