Benjamin was the first U.S. senator to profess the Jewish faith. In 1845, David Yulee, born David Levy, the first cousin of Judah Benjamin’s father, had been sworn in for Florida, but he renounced Judaism and eventually formally converted to Christianity. As an adult, Benjamin married a non-Jew, was not a member of a synagogue, and took no part in communal affairs. He rarely spoke of his Jewish background publicly, but was not ashamed of it. Some of the stories told of Benjamin that touch on this subject come from Rabbi Isaac Mayer Wise, who referred to an address Benjamin delivered in a San Francisco synagogue on Yom Kippur in 1860, though whether this occurred is open to question as Wise was not there and it was not reported in the city's Jewish newspaper. One quote from Senate debate that remains "part of the Benjamin legend", according to Evans, followed an allusion to Moses as a freer of slaves by a Northern senator, hinting that Benjamin was an "Israelite in Egyptian clothing". Benjamin is supposed to have replied, "It is true that I am a Jew, and when my ancestors were receiving their Ten Commandments from the immediate hand of deity, amidst the thunderings and lightnings of Mount Sinai, the ancestors of my opponent were herding swine in the forests of Great Britain." However, this anecdote is likely apocryphal as the same exchange between British Prime Minister Benjamin Disraeli (a converted Jew) and Daniel O'Connell took place in the House of Commons in 1835.
