'Stern' in the Bible

There is stern discipline for one who forsakes the way: whoever hates reproof shall die.

He himself was in the stern, asleep on the cushion, and they woke him up, and told him, "Teacher, don't you care that we are dying?"

Fearing that we would run aground on rocky ground, they let go four anchors from the stern, and wished for daylight.

But coming to a place where two seas met, they ran the vessel aground. The bow struck and remained immovable, but the stern began to break up by the violence of the waves.
