1 Samuel 18:8-11

8And Saul was very wroth, and the saying displeased him; and he said, They have ascribed unto David ten thousands, and to me they have ascribed but thousands: and what can he have more but the kingdom?1 9And Saul eyed David from that day and forward.

10And it came to pass on the morrow, that the evil spirit from God came upon Saul, and he prophesied in the midst of the house: and David played with his hand, as at other times: and there was a javelin in Saul’s hand. 11And Saul cast the javelin; for he said, I will smite David even to the wall with it. And David avoided out of his presence twice.
