'Stern' in the Bible

Then their eyes were opened. And assuming a stern tone Jesus said to them, "Be careful to let no one know."

But He Himself was in the stern asleep, with His head on the cushion: so they woke Him. "Rabbi," they cried, "is it nothing to you that we are drowning?"

Then for fear of possibly running on rocks, they threw out four anchors from the stern and waited impatiently for daylight.

But coming to a place where two seas met, they stranded the ship, and her bow sticking fast remained immovable, while the stern began to go to pieces under the heavy hammering of the sea.
