And in the place of the boil there be a white rising, or a bright spot, white, and somewhat reddish, and it be shewed to the priest;

and in the place of the boil there is a white rising, or a bright spot, reddish-white, then it shall be showed to the priest;

And on the same place there is a white growth of a bright mark, red and white, then let the priest see it;

and there hath been in the place of the ulcer a white rising, or a bright white spot, very red, then it hath been seen by the priest,

And in the place of the ulcer, there appeareth a white scar, or somewhat red, the man shall be brought to the priest.

and there is in the place of the boil a white rising, or a white-reddish bright spot, it shall be shewn to the priest;
