'Loosing' in the Bible

Therefore loosing from Troas, we came with a straight course to Samothracia, and the next day to Neapolis;

And when the south wind blew softly, supposing that they had obtained their purpose, loosing thence, they sailed close by Crete.

And casting off the anchors, they left them in the sea, at the same time loosing the bands of the rudders; and hoisting up the foresail to the wind, they made for the beach.
