'Vial' in the Bible

Then Samuel took the vial of oil, and poured it on his head, and kissed him, and said, "Isn't it that Yahweh has anointed you to be prince over his inheritance?

Elisha the prophet called one of the sons of the prophets, and said to him, "Put your belt on your waist, take this vial of oil in your hand, and go to Ramoth Gilead.

Then take the vial of oil, and pour it on his head, and say, 'Thus says Yahweh, "I have anointed you king over Israel."' Then open the door, flee, and don't wait."
