'Robe' in the Bible

So take a bath, and, after rubbing your body with sweet oil, put on your best robe, and go down to the grain-floor; but do not let him see you till he has come to the end of his meal.

And he said, Take your robe, stretching it out in your hands: and she did so, and he took six measures of grain and put them into it, and gave it her to take: and she went back to the town.
