'Point' in the Bible

At this point, David told Nathan, "I have sinned against the LORD."

But now that he has died, what's the point of fasting? Can I bring him back again? I'll be going to be with him, but he won't be returning to me."

In answer to Joab, Absalom replied, "Look, I sent for you, telling you "Come here so I can send you to the king to ask him "What's the point in moving here from Geshur? I would have been better off to have remained there!"' So let me see the king's face, and if I'm guilty of anything, let him execute me!"

At this point, Zeruiah's son Abishai asked the king, "Why should this dead dog be cursing your majesty the king? May I have permission to go over and cut off his head?"

In response, the king told him, "What's the point of us talking anymore? My decision is that you and Ziba divide the fields."
