Highlights of parashat Va-era`

In this week's parasha, G-d commissioned Moshe to free the people from Egypt.  (G-d has already done this is parashat Shemot, but after the failure of Moshe's first mission, chapter five, then there is a need to start over again.  The difference is that now Moshe was a willing messenger, while before he was a reluctant messenger.)  Afterwards, the Torah records seven of the ten plagues.  We have seven discussions on the parasha on the blog.

One, we discuss why Moshe again mentioned to G-d his speech impediment, http://www.lobashamayim.blogspot.co.il/2009/01/shemot-612-passion-and-speech.html

Three, we discuss what was the plague of arov, http://www.lobashamayim.blogspot.co.il/2015/01/shemot-816-28-arov.html

Five, we discuss the structure and order of the ten plagues.

Seven, we discuss the different terms used to describe the hardening of Pharaoh's heart, on 9:34,35 – The two types of hardening of Pharaoh’s heart, va-yachbed and va-yechezak and two types of thinking, system one and system two
