Moving To A New Existence

The Zohar explains the meraglim sinned because they knew that they would lose their position of נשאים when they entered Eretz Yisroel and they didn't want to be replaced.  How did they know they would lose their position upon entering Eretz Yisroel?
Life in the midbar was a miraculous existence.  There was no need to worry about food, water, lodging etc.all of one's needs were taken care of and one was free to engage in matters of holiness the entire day.  It was paradise on earth.  Moving into Eretz Yisroel wasn't a change in location but a change in life style.  In the holy land there would be no manna, be'ar miriam, annanay hakavod etc.  One would have to work the land to provide for themselves.  Moving into Eretz Yisroel is moving back into olam hazeh.  The נשאים are leaders because they are leaders, those that perfected the avodah of the times.  That avodah of the midbar that they perfected wouldn't be applicable in E.Y. and hence they knew they that would be replaced.  That is what they meant by ארץ אוכלת יושביה, the ארציות, being involved in the daily conduct of earthly affairs will eat us up.
The possuk (14:24) says ועבדי כלב עקב היתה רוח אחרת עמו וימלא אחרי והביאתיו אל הארץ אשר בא שמה וזרעו יורשנה.  Why is Yehoshua omitted, he also shunned the report of the meraglim?  Moshe prayed for Yehoshua קה יושיעך מעצת מרגלים.  Why the name קה?  The Gemorah in Menachos (29b) says עולם הזה was created with a ה and עולם הבא with a י.  Moshe taught Yehoushua the secret of the combo of the י and the ה, that עולם הזה and עולם הבא go hand in hand.  G-d wants for us not to step straight into עולם הבא, but to work for it.  We must have E.Y. as עולם הזה before paradise.  Yehoshua was taught this principle by Moshe; Calev was not.  He didn't have this understanding and still he disagreed with the Meraglim.  He didn't have the answer to the meraglim's complaint of how can we leave the tranquil life of the midbar, yet he knew it wasn't what they were supposed to do.  עבדי כלב, it was his dedication to Hashem that caused him to receive the special yerusha.
In the following parsha of the libations it says כִּ֣י תָבֹ֗אוּ אֶל־אֶ֙רֶץ֙ מוֹשְׁבֹ֣תֵיכֶ֔ם אֲשֶׁ֥ר אֲנִ֖י נֹתֵ֥ן לָכֶֽם.  Why is it called אֶ֙רֶץ֙ מוֹשְׁבֹ֣תֵיכֶ֔ם, an unusual term?  אֶ֙רֶץ֙ מוֹשְׁבֹ֣תֵיכֶ֔ם means the place of dwelling, where the main living is.  Hashem is highlighting immoderately after the meraglim the source of their error.  The way to find G-d is through the hardships of this world.
