Thomas Aquinas, on Ps 50:14
Thomas Aquinas · 1225–1274
Ps 50:14 · Douay-Rheims
“Restore unto me the joy of thy salvation, and strengthen me with a perfect spirit.”
On this verse:
“"Deliver me from bloodguilt." Here he promises the sacrifice of praise; and there are two impediments to this sacrifice. One is the guilt of sin; the other is an interior defect. First, therefore, he asks for the removal of the first impediment. Second, he asks for the removal of the second, at "O Lord, you shall open my lips." He therefore asks for the removal of the impediment and promises the sacrifice of praise. The impediment to divine praise, as has been said, is the guilt of sin. Sir. 15: "Praise is not seemly," etc. Now David was guilty of grave sin; and therefore he asks to be freed from it; and therefore he says, "Deliver me from bloodguilt." According to the Gloss, this noun "blood" is not declined in the plural number; nevertheless, the translator wished to use it to express the sin. And this refers to the concupiscence of the flesh, which is flesh and blood. Mt. 16: "Flesh and blood has not revealed this to you," etc.; as if to say: deliver me from sins committed through flesh and blood. Or it must be said that David had committed the sin of adultery and homicide; and in both there is blood, because in homicide blood is shed. Ps. 5: "The man of blood and deceit," etc. But adultery proceeds from the fervor of blood; and therefore he says, "from bloodguilt." Hos. 4: "Blood has touched blood." O God, deliver me therefore from bloodguilt, because you alone can. Is. 43: "I am he who blots out your iniquities for my own sake," etc. "And because you are the God of my salvation," that is, who can save me. "And my tongue shall exult," namely with delight and with interior joy of heart, "I will declare your justice." Is. 30: "You shall have a canticle as in the night of a sanctified solemnity." Also, ibid. 35: "They shall come to Zion with praise, and everlasting joy shall be upon their heads." Ps. 41: "With the voice of exultation," etc.”
