'Flask' in the Bible

a woman, having an alabaster flask of very precious ointment, came to him and poured it out upon his head as he lay at table.

And when he was in Bethany, in the house of Simon the leper, as he lay at table, there came a woman having an alabaster flask of ointment of pure nard, very costly; and having broken the alabaster flask, she poured it out upon his head.
