It happened, when Abiathar the son of Ahimelech fled to David to Keilah, that he came down with an ephod in his hand.
It is evident that when the will of God was sought through the Urim and Thummim, the person making the inquiry placed the matter before God in prayer and received an answer, but always to one particular question only. David asked two questions in  1 Samuel 23:11, but received an answer to only one of them, so he had to ask the first question a second time.[11]
