'Bottle' in the Bible

And Elisha the prophet sent for one of the sons of the prophets, and said to him, Make yourself ready for a journey, and take this bottle of oil in your hand, and go to Ramoth-gilead.

Then take the bottle and put the oil on his head, and say, The Lord says, I have put the holy oil on you to make you king over Israel. Then, opening the door, go in flight, without waiting.
