Nahum 2:6

Verse 6. The gates of the rivers shall be opened] I have already referred to this, Nahum 1:8; but it will be necessary to be more particular. The account given by Diodorus Siculus, lib. ii., is very surprising. He begins thus: Ην δ' αυτῳ λογιον παραδεδομενον εκ προγονων, κ.τ.λ. - "There was a prophecy received from their forefathers, that Nineveh should not be taken till the river first became an enemy to the city. It happened in the third year of the siege, that the Euphrates [query, Tigris] being swollen with continued rains, overflowed part of the city, and threw down twenty stadia of the wall. The king then imagining that the oracle was accomplished, and that the river was now manifestly become an enemy to the city, casting aside all hope of safety, and lest he should fall into the hands of the enemy, built a large funeral pyre in the palace, (εντοιςβασιλειοις,) and having collected all his gold and silver and royal vestments, together with his concubines and eunuchs, placed himself with them in a little apartment built in the pyre; burnt them, himself, and the palace together. When the death of the king (Sardanapalus) was announced by certain deserters, the enemy entered in by the breach which the waters had made, and took the city."

Thus the prophecy of Nahum was literally fulfilled: "the gates of the river were opened, and the palace dissolved," i.e., burnt.
