'Sink' in the Bible

But when he saw that the wind was strong, he was afraid, and beginning to sink, he cried out, saying, "Lord, save me!"

They beckoned to their partners in the other boat, that they should come and help them. They came, and filled both boats, so that they began to sink.

"Let these words sink into your ears, for the Son of Man will be delivered up into the hands of men."
