A Midrash taught that Eldad and Medad thought that they were not worthy to be among the 70 elders, and in reward for their humility, God gave them several rewards more than the elders: (1) Whereas the elders prophesied only for the next day, Eldad and Medad prophesied what would happen for 40 years. (2) Whereas the elders did not enter the Land, Eldad and Medad did. (3) Whereas the Torah does not tell the names of the elders, it does tell the names of Eldad and Medad. (4) Whereas the prophecy of the elders ended, as it came from Moses, the prophecy of Eldad and Medad came from God.
