Acts 27:27-29

27Now when the fourteenth night had come, as we were drifting across the Adriatic Sea, about midnight the sailors began to sense that they were nearing some land.

28So they took soundings and found the water was twenty fathoms deep. A bit farther along, they took another sounding and found it was fifteen fathoms deep.

29Fearing that we might run aground on the rocks, they threw out four anchors from the stern. They were longing for day to come.
