Matthew 9:17. Neither do men put new wine into old bottles: else the bottles break, and the wine runneth out, and the bottles perish: but they put new wine into new bottles, and both are preserved.
See also Mark 2: 22; Luke 5:37.
The use of bottles made from the skins of animals is very ancient, and is still practiced in the East. The skins of goats and kids are commonly taken for this purpose, and are usually so fashioned as to retain the figure of the animal. In preparing the bottle, the head and feet are cut off, and the skin stripped whole from the body. The neck of the animal sometimes makes the neck of the bottle; in other cases one of the fore-legs is used as all aperture through which the liquid may be poured out. The thighs serve as handles; by attaching straps to them the bottle can be fastened to the saddle, or slung over the shoulder of the traveler. The Arabs tan the skins with Acacia bark and leave the hairy side out. For a large party, and for long journeys across the desert, the skins of camels or of oxen are used. Two of these, when filled with water, make a good load for a camel. They are smeared with grease to prevent leakage and evaporation. These water-skins, large and small, are much better than earthen jars or bottles for the rough experiences of Oriental traveling. Earthen bottles are, however, sometimes employed in domestic use. See note on Jeremiah 19:1 (#545). The “bottle” which Hagar carried into the wilderness, and from which she gave Ishmael drink, was probably a kidskin. See Genesis 21:14. A similar scene is represented in the engraving, from an ancient Assyrian sculpture. Skin-bottles were also used for milk (Judges 4:19) and for wine (1 Sam. 16:20.) In the text and its parallels allusion is made to this use of skins. When the skin is green. it stretches by fermentation of the liquor and retains its integrity; but when it becomes old and dry, the fermentation of the new wine soon causes it to burst.
For the mode of repairing skin-bottles when broken, see note on Joshua 9:4 (#218).
