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 {d} played with [his] hand.
(d) He played on his harp to appease the rage of the evil spirit, 1Sa 16:23.
19:9 The evil spirit - David's successes against the Philistines revived his envy, and the devil watched the opportunity, as he had done before.
19:1-10 How forcible are right words! Saul was, for a time, convinced of the unreasonableness of his enmity to David; but he continued his malice against David. So incurable is the hatred of the seed of the serpent against that of the woman; so deceitful and desperately wicked is the heart of man without the grace of God, Jer 17:9.
