Vv. 10-15 extend the maledictions to the enemy's children and parents, in accordance with the ancient strong sense of family solidarity, which was often expressed in practice by visiting the kindred of a convicted criminal with ruin, and levelling his house with the ground. The psalmist wishes these consequences to fall in all their cruel severity, and pictures the children as vagabonds, driven from the desolation which had, in happier days, been their home, and seeking a scanty subsistence among strangers. The imprecations of ver. 11 at first sight seem to hark back to an earlier stage in the wicked man's career, contemplating him as still in life. But the wish that his wealth may be "ensnared" by creditors and stolen by strangers is quite appropriate as a consequence of his sentence and execution; and the prayer in ver. 12, that there may be no one to "draw out loving-kindness" to him, is probably best explained by the parallel clause. A dead man lives a quasi-life in his children, and what is done to them is a prolongation of what was done to him. Thus helpless, beggars, homeless, and plundered, "the seed of evil-doers" would naturally be short-lived, and the psalmist desires that they may be cut off, and the world freed from an evil race. His wishes go backwards too, and reach to the previous as well as the subsequent generation. The foe had come of a bad stock--parents, son, and son's sons are to be involved in a common doom, because partakers of a common sin. The special reason for the terrible desire that the iniquity of his father and mother may never be blotted out seems to be, the desire that the accumulated consequences of hereditary sin may fall on the heads of the third generation--a dread wish, which experience shows is often tragically fulfilled, even when the sufferers are far less guilty than their ancestors. "Father, forgive them" is the strongest conceivable contrast to these awful prayers. But the psalmist's petition implies that the sins in question were unrepented sins, and is, in fact, a cry that, as such, they should be requited in the "cutting off the memory" of such a brood of evil-doers "from the earth."
