Then the priest shall look upon him; and, behold, if the rising of the plague be reddish-white in his bald head, or in his bald forehead, as the appearance of leprosy in the skin of the flesh;

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;

Then the priest shall look upon him; and, behold, if the rising of the plague be reddish-white in his bald head, or in his bald forehead, as the appearance of leprosy in the skin of the flesh;

Then if the priest sees that the growth of the disease has become red and white on his head or on his brow where there is no hair, like the mark in the skin of a leper;

and the priest hath seen him, and lo, the rising of the very red white plague in the bald back of the head, or in the bald forehead, <FI>is<Fi> as the appearance of leprosy, in the skin of the flesh,

And the priest perceive this, he shall condemn him undoubtedly of leprosy which is risen in the bald part.

And the priest shall look on it, and behold, the rising of the sore is white-reddish in his bald head, or in his bald forehead, like the appearance of the leprosy in the skin of the flesh;
