When Moses had completed the appointment of the elders and had asked them to accompany him to the Tabernacle, there to receive the Holy Spirit, Eldad and Medad, two of these elders, in their humility, did not obey his summons, but hid themselves, deeming themselves unworthy of this distinction. God rewarded them for their humility by distinguishing them five-fold above the other elders. These prophesied what would take place on the following day, announcing the appearance of the quails, but Eldad and Medad prophesied what was still veiled in the distant future.
The elders prophesied only on this one day, but Eldad and Medad retained the gift for life. The elders died in the desert, whereas Eldad and Medad were the leaders of the people after the death of Joshua. The elders are not mentioned by name in the Scriptures, whereas theses two are called by name. The elders, furthermore, had received the prophetic gift from Moses, whereas Eldad and Medad received it directly from God.
