Vaera

G-d tells Moshe to inform the Jewish People that He is going to take them
out of Egypt; however, the Jewish People do not listen. G-d then
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.
G-d punishes the Egyptians and sends plagues of blood and frogs,
but the magicians copy the miracles on a smaller scale,
again encouraging Pharaoh to refuse Moshe's request.

After the plague of lice, even Pharaoh's magicians concede that only
G-d 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 Egypt, Pharaoh continues to harden
his heart and refuses to let them go.
