'Hope' in the Bible

And also the Hope of Israel will not lie nor repent; for he is not a man, that he should repent.

And David said to himself, Some day death will come to me by the hand of Saul: the only thing for me to do is to get away into the land of the Philistines; then Saul will give up hope of taking me in any part of the land of Israel: and so I may be able to get away from him.
