'Mast' in the Bible

And you will be [as unsteady] as one who lies down in the middle of the sea,And [as vulnerable to disaster] as one who lies down on the top of a ship’s mast, saying,

Your ship’s ropes (tackle) hang loose;They cannot hold the base of their mast firmly,Nor spread out the sail.Then an abundance of spoil and plunder will be divided;Even the lame will take the plunder.

“They have made all your planks of fir trees from Senir;They have taken a cedar from Lebanon to make a mast for you.
