Commento biblico di Adam Clarke
1 Samuele 19:9
And the evil spirit from the LORD was upon Saul, as he sat in his house with his javelin in his hand: and David played with his hand. And the evil spirit from the Lord - His envy and jealousy again returned, producing distraction of mind, which was exacerbated by diabolic influence. See on 1 Samuele 16:14 (note).
