For the LORD loveth judgment, and forsaketh not his saints; they are preserved for ever: but the seed of the wicked shall be cut off. Forsaketh not his saints - את חטידיו eth chasidaiv, his merciful or compassionate ones; those who, through love to him and all mankind, are ever ready to give of their substance to the poor.
But the seed of the wicked shall be cut off - The children who follow the wicked steps of wicked parents shall, like their parents, be cut off. God's judgments descend to posterity, as well as his mercies.
