flagon

Boyd’s Bible Dictionary:

(flask). Small vessel for liquids (Isa. 22:24; 2 Sam. 6:19; 1 Chron. 16:3; Song of Sol. 2:5).

Concise Bible Dictionary:

1. ashishah, treated in the A. V. as a measure, but now generally understood to signify a “cake of raisins,” the raisins being pressed into a cake, in the same way that figs are. In 2 Samuel 6:19 and 1 Chronicles 16:3, the words “of wine” have been added. In Song of Solomon 2:5 it is simply “flagons.” In Hosea 3:1 The words “of wine” are not added, but should be translated, as in the margin, “of grapes,” signifying as before “cakes of raisins.”
2. rebel, a bottle, irrespective of its measure (Isa. 22:24). The word is several times translated “bottle.”
