Acts 5:24

They were much perplexed

(διηπορουν). Imperfect active of διαπορεω old verb by Luke only in the N.T. See already on Acts 2:12. They continued puzzled.Whereunto this would grow

(τ αν γενοιτο τουτο). More exactly,As to what this would become

. Second aorist middle optative of γινομα with αν, 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 αν (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!
