1 Samuel 14:2-3

Saul was sitting under a pomegranate tree at the threshing floor near Gibeah. He had about six hundred men with him. One man was Ahijah who was wearing the holy vest. (Ahijah was a son of Ichabod’s brother Ahitub. Ichabod was the son of Phinehas, the son of Eli, the LORD’s priest in Shiloh.) No one knew Jonathan had left.
