29 May his blood fall on the head of Joab and on his whole family! May Joab's family never be without someone who has a running sore or leprosy
29 May it fall upon the head of Joab and upon all his father's house, and may the house of Joab never be without one who has a discharge or who is leprous or who holds a spindle or who falls by the sword or who lacks bread!"
29 Joab and his entire family will always be under the curse of this bloodguilt. May they forever be victims of crippling diseases, violence, and famine."
29 Let it rest on the head of Joab and on all his father's house; and let there never fail to be in the house of Joab one who has a discharge or is a leper, who leans on a staff or falls by the sword, or who lacks bread."
29 Joab and his family are the guilty ones. May the family of Joab be cursed in every generation with a man who has open sores or leprosy or who walks on crutches or dies by the sword or begs for food!"
Matthew Henry's Commentary on 2 Samuel 3:29
Commentary on 2 Samuel 3:22-39
(Read 2 Samuel 3:22-39)
Judgments are prepared for such scorners as Abner; but Joab, in what he did, acted wickedly. David laid Abner's murder deeply to heart, and in many ways expressed his detestation of it. The guilt of blood brings a curse upon families: if men do not avenge it, God will. It is a sad thing to die like a fool, as they do that any way shorten their own days, and those who make no provision for another world. Who would be fond of power, when a man may have the name of it, and must be accountable for it, yet is hampered in the use of it? David ought to have done his duty, and then trusted God with the issue. Carnal policy spared Joab. The Son of David may long delay, but never fails to punish impenitent sinners. He who now reigns upon the throne of David, has a kingdom of a nobler kind. Whatever He doeth, is noticed by all his willing people, and is pleasing to them.
