1 Samuel 14:2-3

And Saul tarried in the uttermost part of Gibeah under a pomegranate tree which is in Migron: and the people that were with him were about six hundred men; and Ahiah, the son of Ahitub, I-chabod's brother, the son of Phinehas, the son of Eli, the LORD's priest in Shiloh, wearing an ephod. And the people knew not that Jonathan was gone.
