The unsung hero in the story of Samuel and Saul is the servant. I am pretty sure I have never heard a sermon about his role in the crowning of Saul as king. He is never named and only referred to as a servant (na ar). He had a “God part” to do and did it well. He is easily compared to Ananias (Acts 9) in the story of Saul the Apostle. He did the job that needed to be done and was never heard of again. Na ar is mentioned nine times before Saul’s signs and only once after them.
In the Strong’s/Vines Concordance the first definition listed is probably not the description of this servant. I think he would have been younger than Saul but not a boy. He was certainly trusted and displayed knowledge of his physical surroundings. He was also spiritually aware because he encouraged Saul to “see the prophet” when he was ready to go home. He had brought his own money, and was willing to use it to resolve the “donkey problem.” He was obedient and loyal to Saul and followed Saul’s leading when the uncle asked about Samuel.
He was honored at the sacrifice because he got to eat with Saul in the main room. But he was not allowed to witness the actual pouring of the oil. He would have seen the results of the anointing because the oil would have been all over Saul’s head. He observed/witnessed the three signs and I cannot believe Saul was not talking about them as they went.
God used an unnamed servant to affect the history of Israel; sometimes we have to do things “just because.” It turned out well for him. Who knows maybe he was Ziba the servant in 2 Samuel 9 who did play a part in the life of lead and the story of Lo Debar.
