'Vial' in the Bible

Then Samuel took the vial of oil, and poured it upon his head, and kissed him, and said, Is it not that Jehovah hath anointed thee to be prince over his inheritance?

And Elisha the prophet called one of the sons of the prophets, and said unto him, Gird up thy loins, and take this vial of oil in thy hand, and go to Ramoth-gilead.

Then take the vial of oil, and pour it on his head, and say, Thus saith Jehovah, I have anointed thee king over Israel. Then open the door, and flee, and tarry not.
