'Unchanged' in the Bible

And the priest shall examine it on the seventh day, and {if}, in his eyes, the infection has stayed [unchanged], the infection has not spread on the skin, then the priest shall confine him [for] seven days second [time].

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, in his eyes, the diseased area of skin has stayed [unchanged] and black hair has grown in it, the diseased area of skin is healed--he is clean, and the priest shall pronounce him clean.
