{Incredible with you} (apiston par' humin). This old word
apiston (a privative and pistos) means either unfaithful
( Lu 12:46 ), unbelieving ( Joh 20:27 ), or unbelievable as
here). Paul turns suddenly from Agrippa to the audience (par'
humin, plural), most of whom were probably Gentiles and scouted
the doctrine of the resurrection as at Athens ( 17:32 ). {If God
doth raise the dead} (ei ho theos nekrous egeirei). Condition
of the first class assuming that God does raise dead people. Only
God can do it. This rhetorical question needs no answer, though
the narrative resumed in verse  9  does it in a way.
