John Gill Bible Commentary

And Saul eyed David from that day and forward. Instead of looking pleasantly, and with a smile, upon him, as a courtier and favourite, he was justly entitled to by his gallant behaviour, he looked at him with a sour, ill natured look; he looked at him with an evil, spiteful, malicious, and envious eye; or he diligently watched and observed all his motions and actions, whether they tended to disloyalty and treason, to dethrone him, and take the kingdom to himself, which he was suspicious of; he laid wait for him, as the Targum, and laid snares too, as the following history shows.

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.
