Let it rest on the head of Joab, and on all his father's house; and let there not fail from the house of Joab one that hath an issue, or that is a leper, or that leaneth on a staff, or that falleth on the sword, or that lacketh bread. Let it rest on the head - All these verbs may be rendered in the future tense: it will rest on the head of Joab, etc. This was a prophetic declaration, which sufficiently showed the displeasure of God against this execrable man.
