***The meaning of the word at the time the New Testament was written is what is important. 125 AD is too late to have any bearing on the writings of the New Testament.***
Think so? Paul's letters were written about 60 years before and there were probably some still alive who remembered him.
John's gospel was written even later and there were definitly some alive then (125 AD)who remembered him.
If the word could mean sprinkling at the time the Holy Spirit inspired the writings of the New Testament, please explain why no NT Greek Lexicon bears that out.
