'Troubling' in the Bible

Now the spirit of the Lord had gone from Saul, and an evil spirit from the Lord was troubling him.

And Saul's servants said to him, See now, an evil spirit from God is troubling you.

And Samuel said to Saul, Why have you made me come up, troubling my rest? And Saul in answer said, I am in great danger; for the Philistines are making war on me, and God has gone away from me and will no longer give me any answer, by the prophets or by dreams: so I have sent for you to make clear to me what I am to do.
