'Again' in the Bible

On the seventh day, the priest is to examine him again. If, in his opinion, the skin rash remained the same and it did not spread, then he is to isolate him for another seven days.

"On the next seventh day, the priest is to examine him again. If the skin rash didn't become dull and it didn't spread in the skin, then the priest is to pronounce him clean: it's a scab. He is to wash his clothes and be clean.

But if, one day, infected flesh appears again in him, he is unclean.
