'Robe' in the Bible

Then Job arose, and rent his robe, and shaved his head, and fell down upon the ground, and worshipped;

And when they lifted up their eyes afar off, and knew him not, they lifted up their voice, and wept; and they rent every one his robe, and sprinkled dust upon their heads toward heaven.

I put on righteousness, and it clothed me: My justice was as a robe and a diadem.
