הִנֵּֽה־בִטְנִ֗י כְּיַ֥יִן לֹא־יִפָּתֵ֑חַ כְּאֹב֥וֹת חֲ֝דָשִׁ֗ים יִבָּקֵֽעַ׃
Behold, mine inwards are as wine which hath no vent; Like new wine-skins which are ready to burst.
Rashi on Job
like wine that is not opened Like new wine that is not opened, and which blows up, and even [if it is] within new wineskins, it bursts them.
