John Wesley on 1 Samuel 23:11

The Lord said - From this place it may appear that God's answer by Urim and Thummim, was not by any change in the colour or situation of the precious stones in the breast - plate of the Ephod, but by a voice or suggestion from God to the high - priest. He will - He purposeth to come, if thou continuest here. For still as David's question, so God's answer, is upon supposition.
