1 Samuel 25:18

Two bottles - Rather, “two skins,” each of which would contain many gallons. These leather vessels varied in size according to the skin they were made of, and the use they were to be put to. The smaller and more portable kind, which may not improperly be called bottles, were made of the skin of a kid: larger ones of the skin of a he-goat. The Arabs invariably to this day carry their milk, water, etc., in such leather vessels. One skin of wine was a handsome present from Ziba, sufficient for David’s household 2 Samuel 16:1. The provisions were all ready to Abigail’s hand, having been provided for the sheep-shearing feast.
