plasterers

1. Yet you are plasterers of lies; Physicians of no value are you all.
    13：4 你们却是以谎言遮饰的，都是无用的医生。

2. The helmet was then molded using the plaster head as a molding ground knowing full well that it would then fit back onto the mask. Once the plasterers had molded the mask and helmet, they were actually cast out in fiberglass with color in the resin so they were black, then maybe they were painted as well.
    石膏面具的头部就等於模具的底部，这样制作出的头盔戴上实际完成的面具时就能完全吻合，石膏师在黏土完成的面具和头盔取模后，就能以石膏模来生产玻璃纤维的成品，玻璃纤维内含染色的树脂所以看起来会是黑的，不过他们之后可能还会再上漆。

plasterers的解释

3. The scientific men and their disciples who suppose they are solving this question are like plasterers set to plaster one side of a church wall, who, in the absence of the chief superintendent of their work, should in the excess of their zeal plaster over the windows, and the holy images, and the woodwork, and the scaffolding, and rejoice that from the plasterers` point of view everything was now so smooth and even.
    那些自以为能解决这个问题的博物学家和他们的信徒，正如这样一些灰泥匠：本来指定他们粉刷教堂的一面墙壁，可是他们趁着总监工不在，一时热情冲动，粉刷了窗子、神像、脚手架，还未加扶壁的墙壁，他们心里很高兴，从他们作灰泥匠的观点来看，一切都弄得又平又光滑。
