Acts 27:27-29

When the fourteenth night had come, as we were being driven across the Adriatic Sea, about midnight the sailors suspected that they were nearing land. So they took a sounding and found twenty fathoms. A little farther on they took a sounding again and found fifteen fathoms. And fearing that we might run on the rocks, they let down four anchors from the stern and prayed for day to come.
