What does Leviticus 13:37 mean?

But if in his eyes the scall be at a stay, and black hair be grown up therein; the scall is healed, he is clean: and the priest shall pronounce him clean.

But if the scall be in his sight at a stay, and that there is black hair grown up therein; the scall is healed, he is clean: and the priest shall pronounce him clean.

But if in his eyes the scall be at a stay, and black hair be grown up therein; the scall is healed, he is clean: and the priest shall pronounce him clean.

But if, in his opinion, the growth is stopped, and black hair has come up on it, the disease has gone; he is clean and the priest will say that he is clean.

and if in his eyes the scall hath stayed, and black hair hath sprung up in it, the scall hath been healed--he <FI>is<Fi> clean--and the priest hath pronounced him clean.

But if the spot be stayed, and the hair be black, let him know that the man is healed: and let him confidently pronounce him clean.

But if the scall have in his sight remained as it was, and there is black hair grown up therein, the scall is healed: he is clean; and the priest shall pronounce him clean.
