"Everybody knows that large flocks of pigeons assemble at the stroke of the great clock in the square of St. Mark, Venice. Believe me, it is not the music of the bell which attacks them, they can hear that every hour. They come, Mr. Preacher, for food, and no mere sound will long collect them. This is a hint for filling your meeting house; it must be done, not merely by that fine, bell-like voice of yours, but by all the neighborhood's being assured that spiritual food is to be had when you open your mouth. Barley for pigeons, good sir; and the gospel for men and women." (Source: Spurgeon's Sermon Notes)
