The parable "Two Sons"
21:28 But what think ye? A certain man had two sons; and he came to the first, and said, Son, go work today in my vineyard.
21:29 He answered and said, I will not: but afterward he repented, and went.
21:30 And he came to the second, and said likewise. And he answered and said, I go, sir: and went not.
21:31 Whether of them twain did the will of his father? They say unto him, The first. Jesus saith unto them, Verily I say unto you, That the publicans and the harlots go into the kingdom of God before you.
21:32 For John came unto you in the way of righteousness, and ye believed him not: but the publicans and the harlots believed him: and ye, when ye had seen it, repented not afterward, that ye might believe him.
