Salmos 137

Salmos 137:8-9

And David, pitying her, says, "O wretched daughter of Babylon." Wretched indeed, as being the daughter of Babylon, when she ceased to be the daughter of Jerusalem. And yet he calls for a healer for her and says, "Blessed is he who shall take your little ones and dash them against the rock." That is to say, shall dash all corrupt and filthy thoughts against Christ, who by his fear and his rebuke will break down all actions against reason, so as, if any one is seized by an adulterous love, to extinguish the fire, that he may by his zeal put away the love of a harlot and deny himself that he may gain Christ. — Concerning Repentance 2.11.106
