'Feel' in the Bible

Let our lord instruct his servants who are here before you to look for a man who knows how to play the lyre. Then whenever the evil spirit from God comes upon you, he can play the lyre and you will feel better."

So whenever the spirit from God would come upon Saul, David would take his lyre and play it. This would bring relief to Saul and make him feel better. Then the evil spirit would leave him alone.

Jonathan said to David, "The Lord God of Israel is my witness. I will feel out my father about this time the day after tomorrow. If he is favorably inclined toward David, will I not then send word to you and let you know?
