'Wine skins' in the Bible

they acted deceptively. They gathered provisions and took worn-out sacks on their donkeys and old wineskins, cracked and mended.

These wineskins were new when we filled them, but look, they are cracked. And these clothes and sandals of ours are worn out from the extremely long journey.”

My heart is like unvented wine;it is about to burst like new wineskins.
