'Loose' in the Bible

at that time spoke Jehovah by Isaiah the son of Amoz, saying, Go and loose the sackcloth from off thy loins, and put off thy sandal from thy foot. And he did so, walking naked and barefoot.

Thus saith Jehovah to his anointed, to Cyrus, whose right hand I have holden, to subdue nations before him and I will loose the loins of kings; to open before him the two-leaved doors, and the gates shall not be shut:

Shake thyself from the dust; arise, sit down, Jerusalem: loose thyself from the bands of thy neck, captive daughter of Zion.

Is not this the fast which I have chosen: to loose the bands of wickedness, to undo the thongs of the yoke, and to send forth free the crushed, and that ye break every yoke?
