Beraisa (R. Yehoshua ben Korcha): The land was divided amongst those who left Mitzrayim and those who stood in the plains of Moav (meaning those that entered the land).

How is this? Whoever left Mitzrayim and also stood in the plains of Moav took two portions. Whoever left Mitzrayim but did not stand in Moav or he stood in Moav but did not leave Mitzrayim, he received one portion.

The daughters of Tzalafchad took five portions of the inheritance - a portion amongst those who left Mitzrayim; a portion amongst those who stood in the plains of Moav; Tzalafchad was the firstborn (thereby meriting a double portion of that estate) and Tzalafchad's portion of his father Chefer's estate that was split with Tzalafchad's brothers.

R. Yosi: The (later) Beraisa does not teach like our Mishnah (that Tzalafchad's daughters took three portions; nor like R. Yehoshua ben Korcha that they took five portions). Rather, it expounds the pasuk (Bamidbar 27:7), "You shall surely give them a portion amongst your father's brothers.'' This implies that there was another brother who died and left his estate to Tzalafchad's daughters. This explains the pasuk that says about Tzalafchad's daughters actual inheritance (Yehoshua 17:2), "And ten portions fell to Menashe'' - he had 6 sons who each took a portion and other four fell to Tzalafchad's daughters.)

Yehoshua and Calev took three portions - that of those who left Mitzrayim; those who stood in Moav and also the portion of the spies, as the pasuk states (Bamidbar 14:38), "And Yehoshua bin Nun and Calev ben Yefuneh survived from the men etc.''

But the portions of the complainers and the assembly of Korach were shared amongst all of Yisrael and the children of these people received a portion from the inheritance of their grandfathers, as the pasuk states (Bamidbar 26:11), "And the children of Korach did not die'' (meaning from receiving a portion of the land).
