I Samuel 14:2-3

And Saul was sitting in the outskirts of Gibeah under a pomegranate tree which is in Migron. The people who were with him were about six hundred men. Ahijah the son of Ahitub, Ichabod’s brother, the son of Phinehas, the son of Eli, the LORD’s priest in Shiloh, was wearing an ephod. But the people did not know that Jonathan had gone.
