'Water vessels' in the Bible

Keep your eyes on the field where they are harvesting, and follow them. I've ordered my young men not to bother you, haven't I? And when you are thirsty, drink from the water vessels that the young men have filled."

Now there were standing there six stone water-vessels, according to the purification of the Jews, holding two or three measures each.

Jesus says to them, Fill the water-vessels with water. And they filled them up to the brim.
