He prophesied - This, as the effect of the evil spirit coming upon him, is singular as regards Saul, but is borne out by what we read in 1 Kings 22:22. (Compare Acts 16:16-18; Acts 19:15; 1 John 4:1-3). It is impossible to give the sense of "raving" to the word "prophesied," as though a merely natural state of frenzy were intended. The "prophesying" here was as directly the effect of the coming of the evil spirit upon Saul, as the "prophesying" in 1 Samuel 10:10 was the effect of the Spirit of God coming upon him. At the same time it is quite true that "madness" and "prophesyings" were considered as near akin (see Jeremiah 29:26; 2 Kings 9:11).

The evil spirit from God - See on 1 Samuel 16:14 (note), etc.

He prophesied in the midst of the house - He was beside himself; made prayers, supplications, and incoherent imprecations: "God preserve my life," "Destroy my enemies," or such like prayers, might frequently escape from him in his agitated state. The Arabic intimates that he was actually possessed by an evil spirit, and that through it he uttered a sort of demoniacal predictions.

But let us examine the original more closely: it is said that Saul prophesied in the midst of his house, that is, he prayed in his family, while David was playing on the harp; and then suddenly threw his javelin, intending to have killed David. Let it be observed that the word ויתנבא vaiyithnabbe is the third person singular of the future hithpael; the sign of which is not only to do an action on or for one's self, but also to feign or pretend to do it. The meaning seems to be, Saul pretended to be praying in his family, the better to conceal his murderous intentions, and render David unsuspicious; who was, probably, at this time performing the musical part of the family worship. This view of the subject makes the whole case natural and plain.

And it came to pass on the morrow,.... After the women had met him with their music and dancing, and when returned home:

that the evil spirit from God came upon Saul; thinking on the above things that had passed, he became melancholy:

and he prophesied in the midst of the house; either really, delivering out divine songs, as the prophets did; according to Abarbinel, he foretold that David would be king, and the kingdom would be taken from him, and given to him; or he feigned himself a prophet, mimicking their motions and gestures; or, as the Targum, acted like a mad man, or a fool, uttering foolish words, and using ridiculous gestures, which seems most agreeable to the evil spirit in him:

and David played with his hand as at other times; upon his harp, to remove the evil spirit, or melancholy disposition from Saul; for though he was now advanced at court, and an officer in the army, and high in the affections and applause of the people: yet he did not think it below him to act as a musician, to do service to his prince; of such an humble, kind, and ingenuous disposition was he:

and there was a javelin in Saul's hand; a kind of spear, or half pike, which he had taken into his hand on purpose to kill David while playing; for persons in such circumstances as his, as they are very mischievous, so very subtle at contriving.

The next day the evil spirit fell upon Saul ("the evil spirit of God;" see at 1 Samuel 16:14), so that he raved in his house, and threw his javelin at David, who played before him "as day by day," but did not hit him, because David turned away before him twice. התנבּא does not mean to prophesy in this instance, but "to rave." This use of the word is founded upon the ecstatic utterances, in which the supernatural influence of the Spirit of God manifested itself in the prophets (see at 1 Samuel 10:5). ויּטל, from טוּל, he hurled the javelin, and said (to himself), "I will pierce David and the wall." With such force did he hurl his spear; but David turned away from him, i.e., eluded it, twice. His doing so a second time presupposes that Saul hurled the javelin twice; that is to say, he probably swung it twice without letting it go out of his hand, - a supposition which is raised into certainty by the fact that it is not stated here that the javelin entered the wall, as in 1 Samuel 19:10. But even with this view יטל is not to be changed into יטּל, as Thenius proposes, since the verb נטל cannot be proved to have ever the meaning to swing. Saul seems to have held the javelin in his hand as a sceptre, according to ancient custom.

And it came to pass on the morrow, that the evil spirit from God came upon Saul, and he {e} prophesied in the midst of the house: and David played with his hand, as at other times: and there was a javelin in Saul's hand.

(e) That is, spoke as a man beside himself for so the people abused this word, when they could not understand.

18:10 The evil spirit, and c. - His fits of frenzy returned upon him. The very next day after he conceived envy at David, the evil spirit was permitted by God to seize him again. Such is the fruit of envy and uncharitableness. Prophesied - That is, he used uncouth gestures, and signs, as the prophets often did.

1Sa 18:10-12. Seeks to Kill Him.

10. on the morrow, that the evil spirit from God came upon Saul-This rankling thought brought on a sudden paroxysm of his mental malady.

he prophesied-The term denotes one under the influence either of a good or a bad spirit. In the present it is used to express that Saul was in a frenzy. David, perceiving the symptoms, hastened, by the soothing strains of his harp, to allay the stormy agitation of the royal mind. But before its mollifying influence could be felt, Saul hurled a javelin at the head of the young musician.

there was a javelin in Saul's hand-Had it been followed by a fatal result, the deed would have been considered the act of an irresponsible maniac. It was repeated more than once ineffectually, and Saul became impressed with a dread of David as under the special protection of Providence.

18:6-11 David's troubles not only immediately follow his triumphs, but arise from them; such is the vanity of that which seems greatest in this world. It is a sign that the Spirit of God is departed from men, if, like Saul, they are peevish, envious, suspicious, and ill-natured. Compare David, with his harp in his hand, aiming to serve Saul, and Saul, with his javelin in his hand, aiming to slay David; and observe the sweetness and usefulness of God's persecuted people, and the barbarity of their persecutors. But David's safety must be ascribed to God's providence.
