The fourth parashah of Torah is heavy reading. From the destruction of an entire city and its people, to immoral sexual acts, to the unfair condemnation of a woman and her child to death, and the willingness of a man to kill his own child. It's tough going. But G-d wants us to read, or listen, and understand this content for two reasons, and those are perhaps the most important lessons we will learn throughout the whole of Torah - what do you do when you are called, and what do you o when the thing you are aked to do conflicts with what you know to be right.  Our Torah characters don't always get it right, and sometimes we learn from their missteps as much as from their triumphs.
