'Unloose' in the Bible
The Lord says this to Cyrus, His anointed, whose right hand I have grasped to subdue nations before him, to unloose the loins of kings, to open the doors before him and the gates will not be shut:
And preached, saying, There cometh one mightier than I after me, the latchet of whose shoes I am not worthy to stoop down and unloose.
John answered, saying unto them all, I indeed baptize you with water; but one mightier than I cometh, the latchet of whose shoes I am not worthy to unloose: he shall baptize you with the Holy Ghost and with fire:
He it is, who coming after me is preferred before me, whose shoe's latchet I am not worthy to unloose.
