레위기 13:48의 주석

לפשתים ולצמר‎ means OF FLAX OR OF WOOL.

Or of wool. The ל is like the ל of (Bereishis 32:18): “למי אתה” which means: To whom do you belong?

.או בשתי, “or in the warp;” the word שתי is not a genitive, construct mode, but a word in its own right, meaning “foundation”. Compare Psalms 11,3: השתות, “the foundations;” the reason is that the warp is the basis of all manner of weaving.

או בעור WHETHER IN A SKIN — this is a skin which has not been manufactured (of which no article has been made).

או בערב, “or in the woof;” the word is so called as it mixes the threads that have to be woven together.

או במלאכת עור OR IN ANYTHING MADE OF SKIN — this is a skin which has been manufactured.
