'Wine skins' in the Bible

they did something clever. They collected some provisions and put worn-out sacks on their donkeys, along with worn-out wineskins that were ripped and patched.

These wineskins we filled were brand new, but look how they have ripped. Our clothes and sandals have worn out because it has been a very long journey."

Inside I am like wine which has no outlet, like new wineskins ready to burst!
