Parable of the Two Sons
The Parable of the Two Sons is a parable told by Jesus in the New Testament, found in Matthew (Matthew 21:28–32). It contrasts the tax collectors and prostitutes who accepted the message taught by John the Baptist with the "religious" people who did not.

Summary
The parable is about 2 sons. Their father asked both of them to work in the vineyard. One of the sons said that he wouldn't do it, but he later changed his mind and did the work anyway. The other son said he would do it, but he didn't.
Interpretation
In this parable, Jesus reproved those who considered themselves virtuous; whereas those they considered sinners, such as the tax collectors and prostitutes, were accepting the message of John the Baptist and repenting. The parable of the Pharisee and the Publican has a similar theme.
