1 The title of the Psalm goes thus. “To the end: for the sons of Korah: a Psalm of David himself.” These sons of Korah have the title also of some other Psalms, and indicate a sweet mystery, insinuate a great Sacrament: wherein let us willingly understand ourselves, and let us acknowledge in the title us who hear, and read, and as in a glass set before us behold who we are. The sons of Korah, who are they?...Haply the sons of the Bridegroom. For the Bridegroom was crucified in the place of Calvary.
Recollect the Gospel, where they crucified the Lord, and you will find Him crucified in the place of Calvary. Furthermore, they who deride His Cross, by devils, as by beasts, are devoured. For this also a certain Scripture signified. When God's Prophet Elisha was going up, children called after him mocking, “Go up thou bald head, Go up thou bald head:” but he, not so much in cruelty as in mystery, made those children to be devoured by bears out of the wood. If those children had not been devoured, would they have lived even till now?
Or could they not, being born mortal, have been taken off by a fever? But so in them had no mystery been shown, whereby posterity might be put in fear. Let none then mock the Cross of Christ. The Jews were possessed by devils, and devoured; for in the place of Calvary, crucifying Christ, and lifting on the Cross, they said as it were with childish sense, not understanding what they said, “Go up, thou bald head.” For what is, “Go up”? “Crucify Him, Crucify Him.” For childhood is set before us to imitate humility, and childhood is set before us to beware of foolishness.
To imitate humility, childhood was set before us by the Lord, when He called children to Him, and because they were kept from Him, He said, “Suffer them to come unto Me, for of such is the Kingdom of Heaven.” The example of childhood is set before us to beware of foolishness by the Apostle, “Brethren, be not children in understanding:” and again he proposes it to imitate, “Howbeit in malice be ye children, that in understanding ye may be men.” “For the sons of Korah” the Psalm is sung; for Christians then is it sung.
Let us hear it as sons of the Bridegroom, whom senseless children crucified in the place of Calvary. For they earned to be devoured by beasts; we to be crowned by Angels. For we acknowledge the humility of our Lord, and of it are not ashamed. We are not ashamed of Him called in mystery “the bald” (Calvus), from the place of Calvary. For on the very Cross whereon He was insulted, He permitted not our forehead to be bald; for with His own Cross He marked it. Finally, that you may know that these things are said to us, see what is said.
