Easton's Bible Dictionary: M. G. Easton, M.A., D.D.
A vessel made of skins for holding wine (Josh. 9:4, 13; 1 Sam. 16:20; Mt. 9:17; Mk. 2:22; Lk. 5:37, 38), or milk (Judg. 4:19), or water (Gen. 21:14, 15, 19), or strong drink (Hab. 2:15).
Earthenware vessels were also similarly used (Jer. 19:1-10; 1 Ki. 14:3; Isa. 30:14). In Job 32:19 (comp. Mt. 9:17; Lk. 5:37, 38; Mk. 2:22) the reference is to a wine-skin ready to burst through the fermentation of the wine. "Bottles of wine" in the Authorized Version of Hos. 7:5 is properly rendered in the Revised Version by "the heat of wine," i.e., the fever of wine, its intoxicating strength.
The clouds are figuratively called the "bottles of heaven" (Job 38:37). A bottle blackened or shrivelled by smoke is referred to in Ps. 119:83 as an image to which the psalmist likens himself.
