'Anchors' in the Bible

Because 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.

Then when the sailors tried to escape from the ship and were lowering the ship's boat into the sea, pretending that they were going to put out anchors from the bow,

So they slipped the anchors and left them in the sea, at the same time loosening the linkage that bound the steering oars together. Then they hoisted the foresail to the wind and steered toward the beach.
