It is the sages’ way to interpret verses and to present the kings of the early empires in a belittling fashion. Thus they explained the words of the prophet Isaiah about Nevuchadnezzar king of Babylon: How you are fallen from heaven,
O day star, son of the dawn! How you are cut down to the ground, you who laid the nations low!” (Isaiah 14:12).
The word “laid ” was interpreted as a lottery. They interpreted the verse to mean that Nevuchadnezzar conducted a lottery amongst his honored guests as to who would have sexual relations with him.
Thus did they interpret the following words by the prophet Isaiah: “All the kings of the nations lie in glory, each in his own house” (Isaiah 14:18) — they rested from the homosexual relations. The sage Rabbi Yochanan added that during the reign of Nevuchadnezzar the subjects were depressed, something which is learned from the words of the prophet Isaiah: “The whole land is at rest and quiet; they break forth in joy” (Isaiah 14:7). After the reign of Nevuchadnezzar ended there was joy amongst the inhabitants of the land; in his era there was no joy. The sage also added that one is forbidden to visit the ruins of Nevuchadnezzar’s house in Babylon, for harmful demons loiter there. A different sage added: When Nevuchadnezzar wanted to have sex with King Tzedkiyahu his membrum grew to a length of 300 amah (150 meters) and surrounded all who were present. How do we know it extended to that length? Because it is written (though it is not clear why they attributed this verse to Nevuchadnezzar) “Woe to him who gives drink to his neighbor, pressing him to your bottle, even to make him drunk,
that you may look on his nakedness. You are filled with shame instead of glory. You also–drink! And be exposed as uncircumcised!” (Habakkuk 2:15-16) This refers to Nevuchadnezzar, who gave Tzedkiyahu wine so he could have sex with him, and at the same time his membrum grew 300 amah, for the word arel [uncircumcised] has a numerical value of 300.
