Exegetical and Hermeneutical Commentary of 1 Samuel 21:14

Then said Achish unto his servants, Lo, ye see the man is mad: wherefore [then] have ye brought him to me?

Ye see the man is mad; and so were Achish and his men too, to be so soon cheated. But this must be ascribed to the wise and powerful providence of God, who, in answer to Davids prayer now made, which is recorded Psa 34; Psa 61, did infatuate them, as he hath done many others in like cases.

Wherefore then have ye brought him to me? what service can I expect from him? or what cause have I to fear him?

Then said Achish to his servants, lo, you see the man is mad,…. Which he said, as willing his servants should think so, and therefore rather the object of their pity than of their rage and malice; or as really believing he was so, which he and they might conclude not merely from these his actions, before described, which they might judge real and not feigned; but they might suppose this was truly his case, brought upon him by the ill usage of Saul, who pursuing him from place to place, and sending after him to take away his life, had really brought him to distraction; and this they might rather conclude from his coming to Gath, an enemy’s country, and whose champion he had slain, and many others of them; which it might be thought no man in his senses would have done:

wherefore [then] have ye brought him to me? for if he was brought to be employed in his service, he seemed very unfit for it, whether in the camp, or in the court; and if to be tried and condemned as an enemy, since he was a madman, he was rather to be pitied.

By this dissimulation David escaped the danger which threatened him; for Achish thought him mad, and would have nothing to do with him. “ Wherefore do ye bring him to me? Have I need of madmen, that ye have brought this man hither to rave against me? Shall this man come into my house? ” Thus Achish refused to receive him into his house. But whether he had David taken over the border, or at any rate out of the town; or whether David went away of his own accord; or whether he was taken away by his servants, and then hurried as quickly as possible out of the land of the Philistines, is not expressly mentioned, as being of no importance in relation to the principal object of the narrative. All that is stated is, that he departed thence, and escaped to the cave Adullam.

(14) Then said Achish . . . the man is mad.The Philistine king would look with peculiar sorrow and repulsion on a madman if, as according to Jewish tradition (see Philippson), his own wife and daughter were insane.

The device, however, succeeded, as David hoped it would, and he was suffered to depart in safetynay, was even hurried out of the Philistine country. In old times, as now, in many parts of the East, the insane are looked upon as persons in some peculiar way possessed by, and therefore under the more immediate protection of, Deity. The life then of the hunted fugitive was perfectly safe from the moment the Philistines considered him mad.
There is a curious legend in the Talmud in which several events recorded in the Biblical account are confused. Part of it apparently refers to this strange choice of his of Phillstia as a place of refuge. One day Satan appeared to him (David) in the shape of a gazelle, which, eluding his pursuit, decoyed him into the land of the Philistines. Ah! said Ishbi-benob, when he caught sight of him, art thou the man that slew my brother, Goliath? So saying, he seized and bound him.Treatise Sanhedrin, fol. 95, cols 1, 2. The wild legend goes on to explain how, partly by miracle, partly with the aid of Abishai, David slew Ishbi-benob and escaped.

14. The man is mad “A sort of respect for persons thus afflicted, as if they were under some kind of supernatural influence, has always existed, and does now exist, in the East; so that David knew his personal safety, and even his freedom, were guaranteed by the belief in his madness.” Kitto.
