Book VII of the Analects is 述而 (Shù ér), named the way all twenty books are — after its own opening words, 述而不作, ‘a transmitter and not a maker.’ The Chinese Text Project ↗ lists it by that romanisation alone, as ‘Shu Er’, and so does Legge. Its chapter numbering is not stable across editions: Legge prints this passage as chapter XV, while the Chinese Text Project lists the identical text as number 16. That is why you will see the same sentence cited as both Analects 7.15 and 7.16 — neither is wrong.
James Legge (1815–1897) produced The Chinese Classics across the 1860s and 70s, with Volume I ↗ — the Analects, the Great Learning and the Doctrine of the Mean — appearing in 1861 and again in a revised edition in 1893. His register is the reason so many Confucius quotations sound faintly biblical in English. Eleven characters of terse classical Chinese become “riches and honours acquired by unrighteousness”: accurate, but unmistakably Victorian.
