John Gill Bible Commentary

And the young man that told him,.... So it seems he was, and therefore could not be Doeg, more likely his son of the two; but there is no reason to believe he was either of them, who cannot be thought to be well disposed to David: said, as I happened by chance upon Mount Gilboa; who was either a traveller that came that way just as the army was routed, and part had fled to Gilboa; or if a soldier, was not one of those that attended Saul, and was of his bodyguard, but happened on the flight to come to the same spot on Gilboa where Saul was: behold, Saul leaned upon his spear; that that might pierce him through and die; but this seems not true, for he fell upon his sword for that purpose, Sa1 31:4, and, lo, the chariots and horsemen followed hard after him; the charioteers and cavalry, of which part of the Philistine army consisted; though this also does not agree with the account in the above place; for according to that they were the archers that pressed him hard, and hit him.
