How many Jews were in the exodus from Mitzraim? Again, let the sources speak.
E: Unknown, but a multitude in the eyes of Moav (Bamidbar 22:3).
J: 600,000 people had to be fed by Moshe, upon exit of Mitzraim. But then, quite immediately, Am Rav, a large multitude, died. How many remained is unknown.
P: 600,000 men, age 20 to 60. So, presumably, at least 2,000,000 people.
D: Like the stars of the skies, for multitude (Devarim 1:9). Significantly, he did not mention the number 600,000. He knew of the large multitude that died, according to J. And he did not know P.
You guessed it: The Halacha is according to J.
