'Bottle' in the Bible

So Abraham got up early in the morning and took bread and a skin of water and gave them to Hagar, putting them on her shoulder, and gave her the boy, and sent her away. And she left [but lost her way] and wandered [aimlessly] in the Wilderness of Beersheba.

When the water in the skin was all gone, Hagar abandoned the boy under one of the bushes.

Then God opened her eyes and she saw a well of water; and she went and filled the [empty] skin with water and gave the boy a drink.
