# my breast is like fermenting wine that has no vent; like new wineskins, it is ready to burst

"I feel like my breast is about to burst, like a container of fermenting wine that has no vent". While wine is fermenting, gas collects in the container. If the gas is not let out the container will burst. Elihu means that he has so much to say that if he does not speak he feels like he will burst.

# my breast is

"my spirit is" or "I am"
