Numbers 11 tells the story of Israel complaining about food in the wilderness. The Targum Jonathan adds a graven image in the camp of Dan, a wind that nearly destroyed the world, and two unauthorized prophets who foretold the apocalypse.
The trouble started with "wicked men of the people" who devised evil. The Targum specifies that the divine fire "destroyed some of the wicked in the outskirts of the house of Dan, with whom was a graven image." This connects the fire at Taberah directly to Dan's later reputation for idolatry (Judges 18).
The people then wept for meat: "We remember the fish which we had to eat in Egypt freely, without being restricted by prohibitory precept." The Targum's addition is pointed. They did not miss the food itself—they missed eating without commandments. Freedom from dietary law was what they craved.
Moses broke under the pressure. He asked God: "Have I made or borne all this people as from the womb?" God responded by appointing seventy elders and amplifying the Spirit of prophecy. The Targum is careful to note that "Moses lost nothing thereof"—the prophetic spirit was shared without being diminished.
Then came Eldad and Medad. The Targum identifies them as sons of Elizaphan bar Parnak, born to Jochebed after Amram had divorced and then remarried her. They remained in the camp, hiding "to escape from the dignity" of eldership. Their prophecies were explosive. Eldad said Moses would die and Joshua would lead Israel into Canaan. Medad predicted the quails would come but cause offense. Together they prophesied the war of Gog and Magog at the end of days: a king would arise from Magog, assemble all nations, and invade Israel—but all would perish "by the burning blast of the flame that comes forth from beneath the Throne of Glory." Afterward, "all the dead of Israel will live again, and be feasted from the ox which has been set apart for them from the beginning."
Joshua urged Moses to silence them. Moses refused: "I would that all the Lord's people were prophets."
