5 And Rechab and Baanah, the sons of Rimmon the Beerothite, went out and came to the house of Ish-bosheth in the heat of the day, when he was resting in the middle of the day. Now the woman who kept the door was cleaning grain, and sleep overcame her. 6 And Rechab and his brother Baanah got in without being seen. 7 And when they came into the house, Ish-bosheth was stretched on his bed in his bedroom; and they made an attack on him and put him to death, and, cutting off his head, they took it with them and went by the road through the Arabah all night.

Commentary on 2 Samuel 4:1-7
(Read 2 Samuel 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.
