4 Now Jonathan, Saul's son, had a son whose feet were damaged. He was five years old when news of the death of Saul and Jonathan came from Jezreel, and the woman who took care of him took him up and went in flight: and while she was getting him away as quickly as she was able, he had a fall and his feet were damaged. His name was Mephibosheth.
Matthew Henry's Commentary on 2 Samuel 4:4
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.
