When the adult Abraham began to preach against idolatry warning of Nimrod's fall, Nimrod had him thrown into a heated furnace; and it was on this account, according to one opinion, that Nimrod was called "Amraphel" ( = "he said, throw in"; Targ. pseudo-Jonathan to Gen. xiv. 1; Gen. R. xlii. 5; Cant. R. viii. 8). When Nimrod was informed that Abraham had come forth from the furnace uninjured, however, he remitted his persecution of the worshiper of Yhwh.
However, the survival of Abraham did not cause Nimrod to change his conduct; he remained an idolater.
===Nimrod's Dream===
The the survival of Abraham did not cause Nimrod to change his conduct; he remained an idolater. The night following the release of Abraham he saw in a dream a man coming out of the furnace and advancing toward him with a drawn sword. Nimrod thereupon ran away, but the man threw an egg at him; this was afterward transformed into a large river in which all his troops were drowned, only he himself and three of his followers escaping. Then the river again became an egg, and from the latter came forth a small fowl, which flew at Nimrod and pecked out his eye. The dream was interpreted as forecasting Nimrod's defeat by Abraham, wherefore Nimrod sent secretly to kill Abraham; but Nimrod's tower fell and Abraham emigrated with his family to the land of Canaan.
Abraham had warned Nimrod not only of the coming destruction but also subjugation to Elam. However, Nimrod had ignored him. According to the "Sefer ha-Yashar" (l.c.), he at this time acquired the name "Amraphel" in allusion to the fall of his princes during the dispersion.
