'Robe' in the Bible

Then Job arose, and tore his robe, and shaved his head, and fell down on the ground, and worshiped.

When they lifted up their eyes from a distance, and didn't recognize him, they raised their voices, and wept; and they each tore his robe, and sprinkled dust on their heads toward the sky.

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