You can think of a heavy book open on a stand, copied by hand long ago. Every word in it is treated as settled: you may read it, learn it and argue about what it means, but you may not change a line of it.
可以想成一本厚厚的書攤開放在架上，是很久以前一個字一個字抄出來的。裡面的每一個字都被當成定案。你可以讀它、背它、討論它的意思，但是你不能改動任何一行。
From the word’s history
Wiktionary records Holy Writ from Middle English Holi Writ, from Old English hāliġ ġewrit, literally 'holy writing'; by surface analysis holy + writ ('scripture, writing').
Wiktionary 記的是中古英文 Holi Writ，再往前是古英文 hāliġ ġewrit，字面就是「神聖的書寫」。拆開來看就是 holy 加 writ（書寫、經文）。這條線索直接對上核心畫面：一本被抄寫下來、一個字都不能改的書。
