'Sport' in the Bible

Why do you make your hearts hard, like the hearts of Pharaoh and the Egyptians? When he had made sport of them, did they not let the people go, and they went away?

Saul told his armor bearer, "Draw your sword and run me through with it, or these uncircumcised people will come and run me through and make sport of me." But his armor bearer did not want to do it because he was very frightened, so Saul took the sword and fell on it.
