Will the men of Keilah deliver me up, to wit, if I continue in their city, and if Saul come down? 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 breastplate of the ephod, but by a voice or suggestion from God to the high priest. He will come down, i.e. he purposeth to come, if thou continuest here; for still, as David's question, so God's answer, is upon supposition, as is here sufficiently implied.
