'Wine skins' in the Bible

they also did work wilily, and went and made as if they had been ambassadors, and took old sacks upon their asses, and wine-skins, old and rent and bound up,

and these wine-skins, which we filled, were new; and, behold, they are rent: and these our garments and our shoes are become old by reason of the very long journey.

Behold, my breast is as wine which hath no vent; Like new wine-skins it is ready to burst.
