1 Samuel 18 & 19 – An evil spirit from Elohim was put on Saul.

1 Sam 19:9
Now there was an evil spirit from the LORD on Saul as he was sitting in his house with his spear in his hand, and David was playing the harp with his hand.

Elohim sent an evil spirit to Saul that made him an unstable man. We have this scene again with David playing his harp for Saul and Saul having his spear in his hand.
