{Didst thou doubt?} (edistasas?). Only here and  28:17 
in the N.T. From distaz(935c) and that from dis (twice). Pulled
two ways. Peter's trust in the power of Christ gave way to his
dread of the wind and waves. Jesus had to take hold of Peter
(epelabeto, middle voice) and pull him up while still walking
on the water.
