'Sink' in the Bible

But when he saw the wind boisterous, he was afraid; and beginning to sink, he cried, saying, Lord, save me.

And they beckoned unto their partners, which were in the other ship, that they should come and help them. And they came, and filled both the ships, so that they began to sink.

Let these sayings sink down into your ears: for the Son of man shall be delivered into the hands of men.
