Exodus 9 - 11
God then strikes the livestock in Egypt, afflicts the Egyptians with boils, and devastates the land of Egypt with destroying hail - yet Pharaoh persists in hardening his heart against the Will of God.
These plagues are followed by locusts that ate up the rest of living plants, and then three days of oppressive darkness in Egypt, but to no avail.
Moses goes out from the presence of Pharaoh, and God then promises to bring one more judgement upon Egypt.
