Acts 12:15

And they said unto her, Thou art mad. But she constantly affirmed that it was even so. Then said they, It is his angel.

And they said unto her, Thou art mad - one of those exclamations which one can hardly resist on hearing what seems far 'too good to be true.'

But she constantly affirmed, [ diischurizeto (G1340)] - 'persisted in affirming'

That it was even so. Then said they, It is his angel - his disembodied spirit, his ghost; anything, in fact, rather than himself. Strange, that though this had been the burden of their fervent prayers, during all the days of unleavened bread, they dispute themselves out of it as a thing incredible. Still, it is but like the unbelief of the disciples who "believed not for joy and wondered" at the tidings of their Lord's resurrection.
