The word "all" is an exaggeration used to emphasize that a great number of Jews wanted Paul to die. Alternate translation: "a great number of the Jews" or "many of the Jewish leaders" (See: [[rc://en/ta/man/jit/figs-hyperbole]])
This statement is made in the negative to emphasize the positive equivalent. Alternate translation: "he should die immediately" (See: [[rc://en/ta/man/jit/figs-litotes]])
