Hashem tells Moshe to inform the Jewish People that He is going to take them out of Egypt. However, the Jewish People do not listen. Hashem commands Moshe to go to Pharaoh and ask him to free the Jewish People. Although Aharon shows Pharaoh a sign by turning a staff into a snake, Pharaoh's magicians copy the sign, emboldening Pharaoh to refuse the request. Hashem punishes the Egyptians, sending plagues of blood and frogs, but the magicians copy these miracles on a smaller scale, again encouraging Pharaoh to be obstinate. After the plague of lice, Pharaoh's magicians concede that only Hashem could be performing these miracles.
Only the Egyptians, and not the Jews in Goshen, suffer during the plagues. The onslaught continues with wild animals, pestilence, boils and fiery hail. However, despite Moshe's offers to end the plagues if Pharaoh will let the Jewish People leave, Pharaoh continues to harden his heart and refuses.
