"No one sews a piece of new, unshrunk cloth on old clothes; otherwise, the patch tears away from it, the new from the old, and makes a worse tear.22 No one pours new wine into old leather wineskins; otherwise, the wine would burst the wineskins and the wine would be lost and the wineskins destroyed. But new wine is for new wineskins."
