'Jars' in the Bible

So he took the jars of the people from their hands, and their trumpets; and he sent all the rest of Israel every man to his tent, but retained the three hundred men; and the camp of Mid'ian was below him in the valley.

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

So Gideon and the hundred men who were with him came to the outskirts of the camp at the beginning of the middle watch, when they had just set the watch; and they blew the trumpets and smashed the jars that were in their hands.

And the three companies blew the trumpets and broke the jars, holding in their left hands the torches, and in their right hands the trumpets to blow; and they cried, "A sword for the LORD and for Gideon!"
