4:4 Jonathan had a son - This history is inserted as that which encouraged these men to this wicked murder, because Saul's family was now reduced to a low ebb; and if Isbosheth was dispatched, there would be none left, but a lame child, who was altogether unfit to manage the kingdom, and therefore the crown must necessarily come to David by their act and deed; for which they promised themselves no small recompense. Jezreel - The place of that last and fatal fight.
4:1-7 See how Ishbosheth was murdered! When those difficulties dispirit us, which should sharpen our endeavours, we betray both our heavenly crowns and our earthly lives. Love not sleep, lest thou come to poverty and ruin. The idle soul is an easy prey to the destroyer. We know not when and where death will meet us. When we lie down to sleep, we are not sure that we may not sleep the sleep of death before we awake; nor do we know from what hand the death-blow may come.
