JMNT(i)
23 Then they were led up [upon the water] (= they shoved off), yet [after a time], during their sailing, He fell asleep. Then a furious, violent windstorm (squall; whirlwind; hurricane) suddenly descended into the lake, and they began being completely filled (swamped) with [water] and continued to be in danger.
24 So then, after approaching, they got Him fully awake, repeatedly saying, "Captain (or: Commander; Chief; = Boss; perhaps: Instructor), we are progressively losing ourselves (or: we, ourselves, are presently perishing)!" Now He, having been fully aroused, gave a respectful directive to the wind and to the violent surging of the water – and it came to be calm (or: a stillness was birthed on the surface of the water).
25 And so He said to them, "Where [is] your confidence, trust and faith?" Now, having been caused to fear (or: being afraid), they marveled with amazement, in turn saying to one another, "Who really is this Man, that to even the winds and to the water He now applies directives (or: gives orders and adds arrangements)? – and in submissive hearing they continue giving obedience to Him!"
