Yes and do you know why we celebrate passover? Because God hardened the Pharaoh’s heart to not let the Isrealites leave Egypt, so He could test these new weapons on Egyptian civilians (who had no power over the Pharaoh). They were plagues and now they’re “battle tested”. And
Every firstborn son in Egypt will die, from the firstborn son of Pharaoh, who sits on the throne, to the firstborn son of the slave girl, who is at her hand mill, and all the firstborn of the cattle as well.
Exodus 11:5
Like with Amalek, not even the cows could catch a break! Pretty violent tradition.
