An animal skin, typically goatskin, sewn and sealed to hold wine. All twelve NT occurrences appear in the famous parable of new wine and old wineskins, recorded in all three Synoptic Gospels (Matt 9:17; Mark 2:22; Luke 5:37-38). Jesus warns that new wine will burst old, brittle skins — the fermentation pressure splits them — so new wine must go into fresh wineskins. The image powerfully illustrates the incompatibility of the new covenant reality with rigid old structures. The word carries no metaphorical ambiguity in the text; it is a concrete household object serving a vivid theological illustration. Spanish 'odres' and French 'outre' both designate the same leather container.
