'Wine skins' in the Bible

they also resorted to a ruse, and went and made as if they had been ambassadors, and took old sacks on their donkeys, and wineskins, old and torn and bound up,

These wineskins, which we filled, were new; and behold, they are torn. These our garments and our shoes have become old because of the very long journey."

Behold, my breast is as wine which has no vent; like new wineskins it is ready to burst.
