I do not know whether this phrases is just a trivial or not a difference at all
from John 4:14 ὃς δι’ ἂν πίῃ ἐκ τοῦ ὕδατος οὗ ἐγὼ δώσω αὐτῷ, (PT)
ὃς δʼ ἂν πίῃ ἐκ τοῦ ὕδατος οὗ ἐγὼ δώσω αὐτῷ, (UBS)
I can read the second line for it is perfectly make sense,
but whoever drink from the water that I will give him
but how about the first line? could it ...
