What does Leviticus 13:39 mean?

then the priest shall look; and, behold, if the bright spots in the skin of their flesh be of a dull white, it is a tetter, it hath broken out in the skin; he is clean.

Then the priest shall look: and, behold, if the bright spots in the skin of their flesh be darkish white; it is a freckled spot that groweth in the skin; he is clean.

then the priest shall look; and, behold, if the bright spots in the skin of their flesh be of a dull white, it is a tetter, it hath broken out in the skin; he is clean.

Then the priest is to see them: and if the white marks on their skin are not very bright, it is a skin disease which has come out on the skin; he is clean.

and the priest hath seen, and lo, in the skin of their flesh white weak bright spots, it <FI>is<Fi> a freckled spot broken out in the skin; he <FI>is<Fi> clean.

The priest shall view them. If he find that a darkish whiteness shineth in the skin, let him know that it is not the leprosy, but a white blemish, and that the man is clean.

and the priest look, and behold, there are in the skin of their flesh pale white spots, it is an eruption which is broken out in the skin: he is clean.
