'Unchanged' in the Bible

The priest will then reexamine him on the seventh day. If he sees that the infection remains unchanged and has not spread on the skin, the priest must quarantine him for another seven days.

But if the spot has stayed [unchanged], it has not spread, it [is] the skin sore's scar, so the priest shall declare him clean.

But if it the spot has stayed [unchanged] in its place, it has not spread on the skin and it [is] faded, [then] it is the burn-spot's swelling, so the priest shall declare him clean, because it [is] the burn-spot's scar.

But if as far as he can see, the scaly outbreak remains unchanged and black hair has grown in it, then it has healed; he is clean. The priest is to pronounce the person clean.
