1 Samuel 18:10-11

It came to pass on the morrow . The day had been a time of public triumph, and yet one of the chief actors goes home to a sleepless couch, because he thinks that another has received higher honour than himself. His melancholy deepens till a fit of insanity comes on. For the evil spirit from God came upon Saul. Literally, " an evil spirit (breath) of God descended mightily upon Saul" (see 1 Samuel 16:15 ). Just as all mighty enthusiasms for good come from God, so do strong influences for evil, but in a different way. In all noble acts men are fellow workers with God; when evil carries them away it is of God, because he it is who has made and still maintains the laws of our moral nature; but it is by the working of general laws, and not by any special gift or grace bestowed by him. Saul had brooded over his disappointment, and cherished feelings of discontent at his own lot and of envy at the good of others to such an extent that his mind gave way before the diseased workings of his imagination. And so he lost all control over himself, and prophesied . The conjugation employed here (Hithpahel) is never used of real, true prophecy (which is always the Niphal), but of a bastard imitation of it. Really Saul was in a state of frenzy, unable to master himself, speaking words of which he knew not the meaning, and acting like a man possessed. In all this there was something akin to the powerful emotions which agitated the true prophet, only it was not a holy influence, but one springing from violent passions and a disturbed state of the mind. In order to soothe him David played with his hand, as at other times, but without the desired effect. On the contrary, Saul brandished the javelin, which he carried as a sort of sceptre in his hand, with such violence that David twice had to escape from this threat of injury by flight. It is not certain that Saul actually threw the javelin. Had he done so it would be difficult to account for David escaping from it twice. After such an act of violence he would scarcely have trusted himself a second time in Saul's presence. Instead of Saul cast the javelin, the Septuagint in the Alexandrian codex and the Chaldee render lifted, i.e. retaining the same consonants, they put vowels which refer the verb to another root. But even with the present vowels it may mean "made as though he would cast," or aimed "the javelin." On a later occasion Saul actually threw the javelin, and struck the wall where David had been sitting ( 1 Samuel 19:10 ).
