Discernment of Spirit

And it came to pass on the morrow, that an evil spirit from God came mightily upon Saul, and he prophesied in the midst of the house: and David played with his hand, as he did day by day: and Saul had his spear in his hand. - 1 Samuel 18:10 RV

and Saul cast the spear; for he said, I will smite David even to the wall. And David avoided out of his presence twice. - 1 Samuel 18:11 RV
