If I remember correctly, the literal word “Jew” did not enter the English language until about 1750. The 1611 King James translation does not contain the letter “J” at all.
Yes, it’s a pretty recent word in English, but there are similar terms in other European languages that are older, and an approximately equivalent term (yehudi) that appears in the Biblical texts.
Ever read The Merchant of Venice? Lots of Jew puns.
