Thomas Aquinas, on Ps 33:21

“The Lord keepeth all their bones, not one of them shall be broken.”

“Then when he says, "The death of sinners," he presents the effects of divine providence with regard to the wicked. And concerning this he does two things. First, the dangers of the wicked are presented. Second, it is shown how God delivers his saints from these, at "The Lord will redeem." Concerning the first he does two things. First, he shows the evil that the wicked suffer in themselves. Second, what threatens them because they persecute the good, at "And those who hate." He says therefore, "Death," corporeal or spiritual. Corporeal death indeed is the worst for the wicked, because they are sent to the worst place. Lk. 16: "The rich man died and was buried in hell." Likewise, because they lose the hope of grace after death. Prov. 11: "When the wicked man dies, there will be no further hope." The death of sinners, therefore, is the worst, because they die both in body and in soul. Spiritual death: Eph. 5: "Rise from the dead." And this death is the worst. For death is the privation of life. Therefore the better the life of which it deprives, the worse the death. Spiritual death deprives the soul of the life of grace, which is the best, because it is through God. 1 Cor. 6: "He who clings to God is one spirit." Therefore it is the worst. Jerome has it thus: "Wickedness shall slay the impious," that is, shall destroy them. This is the wickedness that brings death upon sinners. Rom. 6: "The wages of sin is death." Next he shows what threatens the wicked because they persecute the just. Lk. 10: "He who despises you, despises me." And therefore he says, "And those who hate the just man shall offend." Prov. 29: "Bloodthirsty men hate the upright." If therefore he who hates God will offend, so also he who hates the servants of God.”
