Then the priest shall look upon it: and, behold, if the rising of the sore be white reddish in his bald head, or in his bald forehead, as the leprosy appeareth in the skin of the flesh;

He is a leprous man, he is unclean: the priest shall pronounce him utterly unclean; his plague is in his head.

All the days wherein the plague shall be in him he shall be defiled; he is unclean: he shall dwell alone; without the camp shall his habitation be.

The garment also that the plague of leprosy is in, whether it be a woollen garment, or a linen garment;

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

And if the plague be greenish or reddish in the garment, or in the skin, either in the warp, or in the woof, or in any thing of skin; it is a plague of leprosy, and shall be shewed unto the priest:

And the priest shall look upon the plague, and shut up it that hath the plague seven days:
