The First Time We See the Urim and Thamim Used

It's very likely that whenever the text someone says that some one inquired of the lord, especially if the high priest is present, that they did so by using the urim an thumim. The first time that the objects are explicitly said to be used may be in first samuel 14 during the period when saul is king. At this point in his reign, saul was fighting with the philistines, and things weren't going so well. So saul made a foolish oath. For saul laid an oath on the people, saying, cursed be the man who eats food until it is evening. And i am avenged on my enemies.
