Matthew 14:26

They were troubled (etaracqhsan). Much stronger than that. They were literally "terrified" as they saw Jesus walking on the sea. An apparition (pantasma), or "ghost," or "spectre" from pantazw and that from painw. They cried out "from fear" (apo tou pobou) as any one would have done. "A little touch of sailor superstition" (Bruce).
