Acts 27:27-29

27When the fourteenth night had come, while we were being driven across the Adriatic Sea, about midnight the sailors suspected they were approaching some land.

28They took soundings and found the water was twenty fathoms deep; when they had sailed a little farther they took soundings again and found it was fifteen fathoms deep.

29Because they were afraid that we would run aground on the rocky coast, they threw out four anchors from the stern and wished for day to appear.
