1 Samuel 16:18

Then answered one of the servants
Which the Jews say ^F13 was Doeg the Edomite, who out of envy and ill will to David spake of him, that Saul might have an opportunity of slaying him; but this is not at all likely; rather it was one of David's friends and acquaintance, that was desirous of promoting him at court, and no doubt was directed to that motion by the overruling providence of God:

and said, behold, I have seen a son of Jesse the Bethlehemite;
