In the portion of Vaera things have gone from bad to worse for the Israelite slaves, but God reassures Moses that the redemption will begin. We read about Moses' staff turning into a serpent and the first seven plagues.

The Sidra of Vaera covers the first seven of the ten plagues. If we examine the structure of the plagues, something very interesting emerges:
Plague 1 - Blood: God commands Moses to wait for Pharaoh early in the morning on the banks of the River Nile to warn him that the plague is coming.
Plague 2 - Frogs: God simply instructs Moses to go to Pharaoh, presumably to the royal palace.
Plague 3 - Lice: God tells Moses to initiate the plague without any warning whatsoever.
This pattern repeats itself twice more. Moses waits for Pharaoh on the banks of the Nile in order to announce the fourth plague, wild animals. He goes to Pharaoh to inform him of the fifth plague, pestilence. The sixth plague, boils, is visited on the Egyptians without notice. Plagues seven, eight and nine follow the same template.
What is the significance of this unmistakeable structure? In the sixteenth century, the Maharal of Prague suggested that the pattern of warning and lack of warning reflected Moses's God-directed psychological warfare against Pharaoh. Initially, Moses treated Pharaoh with respect, patiently waiting for him by the river. Next, Moses acted more assertively, approaching Pharaoh when he saw fit rather than waiting for him. Finally, he showed Pharaoh no regard at all, striking Egypt without informing Pharaoh in advance.
A further explanation can perhaps be offered. The Torah is showing us how negative patterns of behaviour, what we might term 'inner plagues', can creep up on us. They begin by waiting patiently; next, they tempt us more directly; ultimately, they become second nature, reflexes which strike without warning and determine our conduct.
The Babylonian Talmud, Tractate Succah 52b, powerfully describes this process:
"Rava said: Initially the Evil Inclination is called 'wayfarer', then it is called 'guest', and finally it is called 'master'".
This is what happens to Pharaoh in our Sidra. The movement from warning to no warning concerning the plagues mirrors the shift in Pharaoh's psyche. Initially, Pharaoh hardens his own heart and refuses to release the Jewish people from slavery. Ultimately, as the text of the Torah indicates, God hardens Pharaoh's heart. Maimonides, in the sixth chapter of Hilchot Teshuvah (Laws of Repentance), among other sources, explains that God took away Pharaoh's free will as punishment for all the sins he had committed when he had free will. According to the line of thought we have been developing, there is no mystery about how God takes away Pharoah's free will. Pharaoh becomes caught in a downward moral spiral, held hostage by his own previous actions and attitudes. He becomes so used to defiance of God and indifference to Israelite suffering that no other mode of behaviour is possible for him any longer.
This kind of negative spiritual dynamic is a danger of which sensitive human beings are aware. The good news is that there is another side to the coin. Positive, upward spiritual momentum is equally possible. Compassion and ethical behaviour can become instinctive. As the Rabbis said in Pirkei Avot (the Ethics of the Fathers): "Aveira goreret aveira" - one sin tends to bring another in its wake. Yet it is also the case that mitzva goreret mitzva - one mitzva often pulls another along behind it.
