Matthew 21:28-31 (NKJV)
“But what do you think? A man had two sons, and he came to the first and said, ‘Son, go, work today in my vineyard.’ He answered and said, ‘I will not,’ but afterward he regretted it and went. Then he came to the second and said likewise. And he answered and said, ‘I go, sir,’ but he did not go. Which of the two did the will of his father?”
They said to Him, “The first.”
