'Anchors' in the Bible

Then fearing that we might run aground somewhere on the rocks, they dropped four anchors from the stern [to slow the ship] and kept wishing for daybreak to come.

But as the sailors were trying to escape [secretly] from the ship and had let down the skiff into the sea, pretending that they were going to lay out anchors from the bow,

So they cut the cables and severed the anchors and left them in the sea while at the same time unlashing the ropes of the rudders; and after hoisting the foresail to the wind, they headed steadily for the beach.
