'Pitchers' in the Bible

And he divided the three hundred men into three companies, and he put into the hands of all of them trumpets, and empty pitchers, with torches within the pitchers.

So Gideon, and the hundred men that were with him, came unto the outermost part of the camp in the beginning of the middle watch, when they had but newly set the watch: and they blew the trumpets, and brake in pieces the pitchers that were in their hands.

And the three companies blew the trumpets, and brake the pitchers, and held the torches in their left hands, and the trumpets in their right hands wherewith to blow; and they cried, The sword of Jehovah and of Gideon.

The precious sons of Zion, comparable to fine gold, How are they esteemed as earthen pitchers, the work of the hands of the potter!
