'Undo' in the Bible

Is not this the fast that I have chosen? to loose the bands of wickedness, to undo the heavy burdens, and to let the oppressed go free, and that ye break every yoke?

Behold, at that time I will undo all that afflict thee: and I will save her that halteth, and gather her that was driven out; and I will get them praise and fame in every land where they have been put to shame.
