{They were much perplexed} (di(8870)oroun). Imperfect active
of diapore(935c) old verb by Luke only in the N.T. See already on
 Ac 2:12 . They continued puzzled. {Whereunto this would grow}
(	i an genoito touto). More exactly, {As to what this would
become}. Second aorist middle optative of ginomai with an,
the conclusion of a condition of the fourth class (undetermined
with less likelihood of determination), the unexpressed condition
being "if the thing should be allowed to go on." The indirect
question simply retains the optative with an (Robertson,
_Grammar_, pp. 1021, 1044). If they had only known how this grain
of mustard seed would grow into the greatest tree on earth and
how dwarfed the tree of Judaism would be beside it!
