שמואל א, פרק ל׳, פסוק ז׳

Seeking guidance, David turns to Abiathar, the son of Ahimelech, who served as the High Priest from the city of Nob. He asks Abiathar to bring the Ephod forward. The specific purpose behind requesting the Ephod is to enable David to seek direction by inquiring of the Urim and Thummim.
