'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.

Moab has been at ease from his youth, and he has been quiet on his dregs, and he has not been poured out from vessel to vessel, and he has not gone into exile. {Therefore} his taste has remained unchanged, and his fragrance has not changed.
