17. the priest shall examine him, and he shall discern him to be clean.
18. But when there has been an ulcer in the flesh and the skin, and it has healed,
19. and in the place of the ulcer, there appears a white or reddish scar, the man shall be brought to the priest.
20. And when he will have seen the place of the leprosy lower than the rest of the flesh, and that the hair has turned white, he shall declare him contaminated. For the plague of leprosy has arisen from the ulcer.
