Bede the Venerable

While the Scribes and Pharisees were murmuring about His receiving sinners, our Saviour put three parables to them successively. In the two first He hints at the joy He has with the angels in the salvation of penitents. But in the third He not only declares His own joy and that of His angels, but He also blames the murmurings of those who were envious. For He says, Now his elder son was in the field.
