Acts 27:27-29

27Now when the fourteenth night had come, as we were driven up and down in the Adriatic Sea, about midnight the sailors sensed that they were drawing near some land.

28And they took soundings and found it to be twenty fathoms; and when they had gone a little farther, they took soundings again and found it to be fifteen fathoms.

29Then, fearing lest we should run aground on the rocks, they dropped four anchors from the stern, and prayed for day to come.
