- 30 And approaching the other, he spoke similarly. And answering, he said, ‘I am going, lord.’ And he did not go.
- 31 Which of the two did the will of the father?” They said to him, “The first.” Jesus said to them: “Amen I say to you, that tax collectors and prostitutes shall precede you, into the kingdom of God.
- 32 For John came to you in the way of justice, and you did not believe him. But the tax collectors and the prostitutes believed him. Yet even after seeing this, you did not repent, so as to believe him.

Citations as published in the USCCB liturgical calendar.

In US parishes the readings are proclaimed from the NABRE; the text shown here is the Catholic Public Domain Version.

Old Testament readings and the psalm are listed with a link to their chapter: the US Lectionary numbers some of their verses differently from the CPDV, so their text is not printed here. Psalm citations keep the Lectionary’s Hebrew numbering; the CPDV numbers the Psalms as the Vulgate does.
