Discovery BoxMatthew 21:29 
Context21:29 The boy answered, 1 ‘I will not.’ But later he had a change of heart 2 and went.
Matthew 21:32
Context21:32 For John came to you in the way of righteousness, and you did not believe him. But the tax collectors and prostitutes did believe. Although 3 you saw this, you did not later change your minds 4 and believe him.
1 tn Grk “And answering, he said.” This is somewhat redundant and has been simplified in the translation. Here the referent (“the boy”) has been specified in the translation for clarity.
2 tn The Greek text reads here μεταμέλομαι (metamelomai): “to change one’s mind about something, with the probable implication of regret” (L&N 31.59); cf. also BDAG 639 s.v. The idea in this context involves more than just a change of mind, for the son regrets his initial response. The same verb is used in v. 32.
3 tn Here δέ (de) has not been translated.
4 sn The word translated change your minds is the same verb used in v. 29 (there translated had a change of heart). Jesus is making an obvious comparison here, in which the religious leaders are viewed as the disobedient son.
