(28) Sela-hammahlekoth.--Literally, as in the margin of our Bibles, the rock (or, still better, the cliff) of divisions. Other scholars, with greater reason, prefer the derivation from a Hebrew word signifying to be smooth--the cliff of smoothness: that is, of slipping away or escaping. Ewald rather fancifully interprets the term as the "Cliff of Destiny or of Fate."
23:19-29 In the midst of his wickedness, Saul affected to speak the language of piety. Such expressions, without suitable effects, can only amuse or deceive those who hear, and those who use them. This mountain was an emblem of the Divine Providence coming between David and the destroyer. Let us not be dismayed at the prospect of future difficulties, but stay ourselves upon Him who is wonderful in counsel and excellent in working. Sooner than his promise shall fail, he will commission Philistines to effect our escape, at the very moment when our case appears most desperate. God requires entire dependence on him, If ye will not believe, surely ye shall not be established, Isa 7:9.
Therefore Saul returned from pursuing after David,.... Stopped short at once, as soon as ever he received the message:
and went against the Philistines; to stop them in their progress, and drive them out of his country:
therefore they called that place Selahammahlekoth, which signifies the rock of divisions. David and his men, very probably, gave it this name, not only because it divided between Saul and his men, and David and his men, when they were one on one side of it, and the other on the other side of it; but because Saul was, by the providence of God, divided and separated from David here, whereby he escaped falling into his hands. The Targum is,"therefore they called that place the rock of division, the place where the heart of the king was divided to go here and there:''he was divided in his own mind, and at a loss what to do; he was in two minds, as Jarchi says, and did not know which to follow, whether to return and deliver his country from the hands of the Philistines, or to pursue and take David; and others represent the soldiers of Saul as divided, some saying that since the son of Jesse was just falling into their hands, they should not leave him; others, that the war of Israel should be regarded before him, who might be found at any time (u).
