{But should we say} (alla eip(936d)en). Deliberative
subjunctive with aorist active subjunctive again. It is possible
to supply ean from verse  31  and treat it as a condition as
there. So  Mt 21:26  and  Lu 20:6 . But in Mark the structure
continues rugged after "from men" with anacoluthon or even
aposiopesis--"they feared the people" Mark adds. Matthew has it:
"We fear the multitude." Luke puts it: "all the people will stone
us." All three Gospels state the popular view of John as a
prophet. Mark's "verily" is ont(9373) really, actually. They feared
John though dead as much as Herod Antipas did. His martyrdom had
deepened his power over the people and disrespect towards his
memory now might raise a storm (Swete).
