Turn, O Lord, our captivity, like a torrent in a south wind (Ps 125:4). As torrents in a south wind are turned, so turn our captivity. Someone asked, "What does this mean?" ... Somewhere Scripture, commanding and warning us with regard to good deeds, says: Like ice on a bright day, so will your sins be melted (Sirach 3:17). Our sins, therefore, were binding us. How? The way cold binds water so it cannot run. And bound by the cold of our sins, we had turned to ice. A south wind is a warm wind, and when there is a south wind, ice melts, and the torrents are filled. Torrents are winter floods; suddenly filled with water, they run with great force. We had turned to ice, therefore, in our captivity; our sins were holding us fast. A south wind, the Holy Spirit, blew over us, and our sins were forgiven us; we were freed from the cold of wickedness; like ice on a bright day, our sins are melted away. Let us rush toward our homeland, like torrents in a south wind. [Augustine, Enarr. in Ps 125,10; PL 37:1663-64]... flavit auster Spiritus sanctus.
