'Flask' in the Bible

The prophet Elisha called one of the sons of the prophets and said, “Tuck your mantle under your belt, take this flask of oil with you, and go to Ramoth-gilead.

Then, take the flask of oil, pour it on his head, and say, ‘This is what the Lord says: “I anoint you king over Israel.”’ Open the door and escape. Don’t wait.”
