And Pharao sent to see; and there was not any thing dead of that which Israel possessed. And Pharao's heart was hardened, and he did not let the people go.
וַיִּשְׁלַ֣ח פַּרְעֹ֔ה וְהִנֵּ֗ה לֹא־מֵ֛ת מִמִּקְנֵ֥ה יִשְׂרָאֵ֖ל עַד־אֶחָ֑ד וַיִּכְבַּד֙ לֵ֣ב פַּרְעֹ֔ה וְלֹ֥א שִׁלַּ֖ח אֶת־הָעָֽם׃
2 Church Fathers comment on this verse
God inflicted death upon the livestock, yet He distinguished between the cattle of the Israelites and those of the Egyptians. When this did not persuade Pharaoh to release the people, Moses, in plain view of Pharaoh, ‘scattered the ashes of the furnace.... scattered... ‘and boils broke out... ‘on both humans and animals. The cattle could not endure the presence of Moses.
Pharaoh likely believed that the safety of Israel's livestock was due to their superior care and the favorable conditions in which they thrived, rather than acknowledging it as a result of divine safeguarding. This tendency towards self-deception and refusal to recognize God's disciplining hand is a prevalent human flaw.
