Matthew Poole and continuators on Leviticus 13:48

48 Whether it be in the warp, or woof of linen or of woollen, whether in a skin, or in any thing made of skin:

A learned man renders it, in the outside, or in the inside of it. If the signification of those words be doubtful or unknown now, as some of those of the living creatures and pretious stones are confessed to be, it is not material to us, this law being abolished: it sufficeth that the Jews understood these things by frequent experience.
