Bo - Tzivos Hashem

Parshat Bo - Tzivos Hashem (12:41)

"At the end of 430 years, on that very day, all the armies of Hashem (tzivos Hashem) left Egypt" (12:41).

The word "tzava" is an army.  "Tzivos Hashem" is plural - the armies of G-d.  What armies of G-d left Egypt?

Torah Shleima cites the Mechilta which says: When Israel is in exile, the Divine Presence goes in exile with them.  So when the Jews left Egypt, the Shechina, along with the angels that make up the King's household (the entourage) left Egypt.  And the Zohar says since the Jews did not marry Egyptian women, they received G-d Name (as a seal attesting to their purity).  So "Tzivos Hashem" either refers to angels who left Egypt when the Jews left, or it refers to the Jews themselves.

Tziva'os is often used as a name of G-d.  Why?  Rashi (Devarim 12:2) says an "os" is something in the heavens, and a "mofes" is something on the earth.  (Similarly in this week's Parsha [11:10] Moshe and Aharon did "mofsim" which Rashi says were Makas Bechoros, Splitting the Sea, and the Egyptians dying in the Sea - all thses were incidents on earth.)  So the word "Tziva'os" is likely on contraction of the words "tzava," army, and "os," which is something that happens in the heavens.  Hashem created the constellations and heavenly bodies, and set them in their orbits (see Rambam Hilchos Yeshodei Hatorah chapter 3) and their movements and orbits testify to G-d's creating the world, and they are the entourage of Hashem.
