John 7:31

ἐκ τ. ὀχλ. δὲ π. But (on the other hand, i.e. in contrast to the rulers) of the multitude many believed on Him (as the Messiah) and kept saying (in answer to objectors), When the Christ (see on John 7:27 and John 1:20) cometh, will He do more signs than those which this man did? They express, not their own doubts, but those of objectors in saying, ‘when the Christ cometh:’ they believe that He has come. Some of them perhaps had witnessed the numerous Galilean miracles; they have at any rate heard of them, and it is on them, not on His teaching and work, that their faith is based; hence its weakness. Winer, p. 641.
