Psalms 109:13
Let his posterity be cut off - To have a numerous posterity, to have the name and family perpetuated, was regarded among the Hebrews as one of the greatest and most desirable blessings. Hence, to pray that all one' s family might be cut off was one of the severest forms of malediction which could be employed.
And in the generation following - The very next generation. Let not his family be perpetuated at all.
Let their name be blotted out - As a name is erased from a catalogue or muster-roll when one dies.
