Orthodox Jewish Bible

⁵⁵ And the kohen shall examine the nega, after that it is washed; and, hinei, if the nega has not changed its appearance, and the nega be not spread, it is tamei; thou shalt burn it in the eish; whether the eating away hath brought bareness in the front or back.

⁵⁶ And if the kohen examine, and, hinei, the nega be somewhat faded after the washing of it, then he shall tear it out of the garment, or out of the leather, or out of the warp, or out of the woof;
