Matthew 21:26-30

“But what do you think? A man had two sons, and he came to the first and said, ‘ Son, go work today in the vineyard.’

But he replied, ‘I do not want to.’ Yet afterward he regretted it and went.

And the man came to his second son and said the same thing; and he replied, ‘I will, sir’; and yet he did not go.
