Is 'Passover' Actually a Mistranslation?

A few years ago, I learned that I'd been misled about Passover for my entire life. Jews will begin celebrating this holiday, which commemorates the exodus of the enslaved Israelites from ancient Egypt, on Friday night. In the Hebrew Bible, this festival is called "Pesach." In English, it is known as "Passover." But what if that's a mistake? Back in 2019, thanks to Joe Septimus, a member of my New York synagogue, and his brother Bernard Septimus, my teacher at Harvard, I discovered that according to the original Jewish sources, "Passover" is far from the most intuitive translation of the holiday's name.
