To see Saul, i.e. to visit him, either in token of respect or friendship; or to seek counsel from God for him, or to give counsel to him. Seeing is put for visiting here, and 2 Kings 8:29. Otherwise he did see him afterwards, 1 Samuel 19:24. Though indeed it was not Samuel that came thither with design to see Saul, which is implied in the phrase here; but Saul went thither to see Samuel, and that accidentally. Samuel mourned for Saul; partly for Saul's sake, whose sad condition he lamented; and partly for Israel's sake, whose estate he feared might by this means be doubtful and dangerous.
