The author of 2 Samuel sets the events of chapters 9 and 10 right beside each other. In both, David is showing kindness. In one it is accepted and changes Mephibosheth's life forever. Now, in chapter 10, it is rejected. Not merely ignored - rejected. We find David to be slow to anger ... In all of this we are, again, pointed to the Lord Jesus Christ and the folly of rejecting His offer of salvation.
