Boyd’s Bible Dictionary:

Concise Bible Dictionary:
There are six Hebrew words translated “bottle” in the Old Testament. Among the descendants of Judah there were some described as “potters” (1 Chron. 4:23); and from the relics found in the tombs of Egypt it is evident that bottles were very early made of earthenware; and small ones of glass; though then, as now in the East, especially for larger vessels and for those to be carried about, skins were used (Josh. 9:4, 13). They are made of goats’ skins: the head, the legs and the tail are cut off, and the body drawn out. In the New Testament the word is ἀσκός, and signifies a “wineskin,” or “skin-bag.” Hence new wine must be put into new skins, which are more or less elastic (Matt. 9:17; Mark 2:22; Luke 5:37-38). The Lord was teaching that the new principles of the kingdom would not suit the old forms of Judaism: everything must be new.
