Shlach 1

For Moshe's Benefit:
The pasuk says (13:2) "Send for you, men..." The mefarshim explain why Hashem says "for you" to mean that the it was for Moshe's benefit. The Moshav Zekainim explains what this means. From the prophecy from last week it was known that Moshe was destined to die before the Jews entered the land. If they were to enter now Moshe would die. Now that they were sending meraglim it would cause the Jews to spend an extra forty years in the desert. Now that the Jews would spend more time in the desert Moshe would live longer.This is why it was for Moshe's benefit.

Meraglim:

When the meraglim came back they told the people that the nations that live in the land are stronger than them and that they could not possibly beat them in war. How could the meraglim say this? They had Hashem on their side, how could they possibly lose? Ever since the people started complaining last week for meat the entire nation's level changed. They were no longer on the same level they had once been. The people had now become enticed by physical pleasures. Once this happened they lost their ability to be spiritual and truly believe in Hashem. It was for this reason why they sent meraglim in the first place, because they lost faith. Now after hearing that they would lose their leader Moshe they thought they would have no chance, that all of their power as a nation came from Moshe. I saw it explained that this was the reason why Caleiv had to speak up. He had to tell the people that it was not Moshe who made them what they were but rather it was them who made Moshe what he was. Since the people lost faith so too Moshe did not have as much faith, that is why he sent the spies. The reason why the meraglim said that the other nations where stronger and that the Jews could not win is because of their lose of faith. It was true, without Hashem victory was impossible, they had no chance of survival. What they said was 100% true, if you take Hashem out of the equation you have no chance. The survival of the Jews is completely based on Hashem, we do not exist without Him. This is the reason for all future events in that generation, and for this reason there was no way the the people of that generation could go into the land, because they could not win without Hashem.

Last Years Dvar Torah:
Last week we learned that Moshe was destined to die in the desert and Yehoshua was going to lead the Jews into the land. There was only one problem, until now there was no one named Yehoshua, he was named Yoshaia. The Zohar explains that the reason he is called Yehoshua before his name was changed was in anticipation. The zohar explains that the meraglim thought that going into the land would make them lose their power.So when the meraglim were chosen they saw no problems. They would go to the land and say how good it was but they knew that as long as they were not going to actually go to the land because there was no Yehoshua to take them in. Rashi says in pasuk 3 on the word "anashim" "...at this time they kesharim" then it says in pasuk 26 in Rashi "that just as their returning was for evil so too there coming was for evil." What happened between there being chosen and their becoming evil? The only event was Yoshaia's name being changed to Yehoshua, and this is the reason why they spoke badly about the land.
