Origen
Catena Aurea · Lukasevangelium 3
And the people asked him, saying, What shall we do then? He answereth and saith unto them, He that hath two coats, let him impart to him that hath none; and he that hath meat, let him do likewise. Then came also Publicans to be baptized, and said unto him, Master, what shall we do? And he said unto them, Exact no more than that which is appointed you. And the soldiers likewise demanded of him, saying, And what shall we do? And he said unto them, Do violence to no man, neither accuse any falsely; and be content with your wages.
Three classes of men are introduced as enquiring of John concerning their salvation, one which the Scripture calls the multitude, another to which it gives the name of Publicans, and a third which is noticed by the appellation of soldiers.
