'Loose' in the Bible

As for all the hills which used to be cultivated with the pick and the hoe, you will no longer go there for fear of briars and thorns; but they will become a place where oxen are pastured and where sheep tread.

at that time the Lord spoke through Isaiah the son of Amoz, saying, “Go, untie the sackcloth from your hips and take your sandals off your feet.” And he did so, walking around stripped [to his loincloth] and barefoot.

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.

Shake yourself from the dust, arise,O captive Jerusalem;Rid yourself of the chains around your neck,O captive Daughter of Zion.

“[Rather] is this not the fast which I choose,To undo the bonds of wickedness,To tear to pieces the ropes of the yoke,To let the oppressed go freeAnd break apart every [enslaving] yoke?
