SEV Biblia, Chapter 7:29
Entonces le dice: Por esta palabra, ve; el demonio ha salido de tu hija.
John Gill's Bible Commentary
Ver. 29. And he said unto her, for this saying , etc..] Or word of faith; in which she expressed such great faith in him: the Persic version reads it, go thy way; for with the blessing of this word, the devil is gone out of thy daughter: as if this saying referred to the word Christ, and the divine power that went along with it, to the ejection of the devil; when it refers to the saying of the woman, and not to the words of Christ, which follow, go thy way ; in peace, thy request is granted; it is as thou wouldst have it: the devil is gone out of thy daughter . Christ, who as God is every where, and whose divine power reaches to all places, persons, and things had, in a secret and powerful manner, cast the devil out of this woman's daughter; without going to her, or speaking to him, his power had wrought the miracle effectually.
Matthew Henry Commentary
Verses 24-30 - Christ never put any from him that fell at his feet, which a poor trembling soul may do. As she was a good woman, so a good mother. Thi sent her to Christ. His saying, Let the children first be filled, show that there was mercy for the Gentiles, and not far off. She spoke, no as making light of the mercy, but magnifying the abundance of miraculous cures among the Jews, in comparison with which a single cur was but as a crumb. Thus, while proud Pharisees are left by the blesse Saviour, he manifests his compassion to poor humbled sinners, who loo to him for children's bread. He still goes about to seek and save the lost.

Robertson's NT Word Studies
7:29 {For this saying} (dia touton ton logon). She had faith, great faith as #Mt 15:28 shows, but it was her quick and bright repartee that pleased Jesus. He had missed his rest, but it was worth it to answer a call like this .
