Ellicott's Commentary On The Whole Bible
1 Samuel 10:8
And shew thee what thou shalt do. — Considerable doubt exists among expositors as to the exact meaning and reference of these words of Samuel. In 1 Samuel 13., 1 Samuel 10:8 and following, a well-known and most important event in Saul’s life and reign is related, in which the circumstances strangely fit in with the words of the warning of Samuel. Only between this first meeting of the seer and the future king and the Gilgal meeting, described in 1 Samuel 13., two years — perhaps even a much longer period — elapsed (the dates of this age are most uncertain); besides which, that famous meeting at Gilgal was not by any means the first meeting of Samuel and Saul at that place. Yet, in spite of these difficulties, it seems best to refer to this meeting between the prophet and king at Gilgal, related in 1 Samuel 13, as the trial of faith especially looked on to by Samuel here. The solemn warning here given was, doubtless, repeated in a much more detailed form by the prophet some time before the appointed Gilgal meeting. So much for the reference; the signification of the warning is best explained in the following way: — Samuel had bidden the future king to advance along the paths of glory and difficulty which lay before him in all confidence and trust, acting in each emergency according to the dictates of his own heart — only in one thing he must be ever on his guard. In his future great work for the regeneration and advancement of Israel, he must, for the sake of the faith of Israel, be on his guard against infringing the sacred privileges of the religion of the Eternal. In the plenitude of his kingly power, the day would come when the temptation would assault him to disregard the ancient sanctity of the sacrifice, and to assume as king, functions which belonged alone to men like Samuel set apart for the sacred office, and thus publicly to dishonour the commandments of God, and by his reckless example of unbelief in revelation to weaken the faith of the people.
Such a temptation presented itself to Saul, we believe, some two or more years from this time, when, as related in 1 Samuel 13, a solemn assembly of the people was summoned to Gilgal, before the commencement of the war of independence. This great enterprise for the people of the Lord must necessarily be begun with solemn religious rites and sacrifices. These the king was forbidden to officiate at without the presence of the Divinely appointed seer. We shall see how King Saul acted under the temptation to set himself and his royal power above the prophet of the Lord and the direct command of God. Whether or no King Saul with his own hand offered the Gilgal sacrifice is uncertain; at all events, the great sin he seemed to have been guilty of having committed, is to have declined to wait for the presence of the prophet of the Lord, although publicly required by the word of the Lord to do so. (See Notes on 1 Samuel 13)
The “heart” is mentioned as changed by God, because, according to the conception of the Divine writings, the heart is represented as the centre of the whole mental and physical life — of will, desire, thought, perception, and feeling. It was one thing for Samuel the seer to put before the young Benjamite the brilliant destiny which lay before him, but it was another and different thing to transform one like Saul, brought up to merely agricultural pursuits, into a fit and worthy recipient of such honours and powers. We know how utterly incapable are all such things as wealth and rank and power in themselves of inspiring the heart with any noble patriotic aspirations, or with any high religious longings, or lofty patriotic aims; a higher influence is needed to awaken the heart, or to rouse it from merely earthly and sordid contemplations.
This is the work which God worked in the heart. of the young Saul as, in the early morning, he left “Ramah of the Watchers,” his ears tingling with the burning words of the great seer all through that day and many succeeding days. In quiet humility, and, no doubt, with many a silent prayer, he watched and waited; when he returned home there was no sign of exultation visible in the man, no mark of impatience. His lips were sealed; he seems to have whispered to no one what the prophet had told him; he made no sign even when events came crowding thick about him — such as the popular assembly for the choice of a king, presided over by the prophet-judge, whose mind Saul alone in Israel knew: the drawing of the lots: the narrowing of the fateful circle: the designation of his tribe, his family, then himself. We see, indeed, God had changed his heart. Was there not in these early days a promise of a noble king — a man after God’s own heart?
And all those signs came to pass that day. — Of the first two signs which were to meet him no further details are given; we are simply told that in the order predicted by Samuel Saul came across them. The third alone gives occasion for a special mention, because it had a great effect on the life of the future king.
