'Wine skins' in the Bible

"Nor do they put new wine into old wine-skins; if they did, the wine-skins would split, the wine would run out, and the skins be ruined. Instead, they put new wine into fresh wine-skins and both are preserved."

And no one ever pours new wine into old wine-skins, else the wine would burst the skins, and both wine and skins would be lost. New wine is poured into fresh wine-skins.

"Nor does any one pour new wine into old wine-skins; otherwise the new wine will burst the skins, and will itself be spilled, and the skins be destroyed

"But new wine must be put into fresh wine-skins
