Charles Ellicott Commentary Psalms 109:9

"Let his children be fatherless, And his wife a widow." — Psalms 109:9 (ASV)

Children ... wife. —It is one of the sadly peculiar features of this series of curses that the resentment of the imprecator cannot satisfy itself on the person of his enemy, but fastens also on his innocent descendants. To invoke a speedy death does not satisfy him; he must feast his anger with the thought of the fatherless children and desolate widow.
