Bede the Venerable

For Pilate, who is interpreted, “The mouth of the hammerer,” signifies the devil ever ready to strike. The blood expresses sin, the sacrifices good actions. Pilate then mingles the blood of the Galilæans with their sacrifices when the devil stains the alms and other good works of the faithful either by carnal indulgence, or by courting the praise of men, or any other defilement. Those men of Jerusalem also who were crushed by the falling of the tower, signify that the Jews who refuse to repent will perish within their own walls. Nor without meaning is the number eighteen given, (which number among the Greeks is made up of Ι and Η, that is, of the same letters with which the name of Jesus begins.) And it signifies that the Jews were chiefly to perish, because they would not receive the name of the Saviour. That tower represents Him who is the tower of strength. And this is rightly in Siloam, which is interpreted, “sent;” for it signifies Him who, sent by the Father, came into the world, and who shall grind to powder all on whom He falls.
