Matthew 15:5

But ye say, Whosoever shall say to his father or his mother, It is a gift--or simply, "A gift!" In Mark (Mar 7:11), it is, "Corban!" that is, "An oblation!" meaning, any unbloody offering or gift dedicated to sacred uses. by whatsoever thou mightest be profited by me;

In this chapter, we have our Lord Jesus, as the great Prophet teaching, as the great Physician healing, and as the great Shepherd of the sheep feeding; as the Father of spirits instructing them; as the Conqueror of Satan dispossessing him; and as concerned for the bodies of his people, providing for them. Here is, I. Christ's discourse with the scribes and Pharisees about human traditions and injunctions (Mat 15:1-9). II. His discourse with the multitude, and with his disciples, concerning the things that defile a man (Mat 15:10-20). III. His casting of the devil out of the woman of Canaan's daughter (Mat 15:21-28). IV. His healing of all that were brought to him (Mat 15:29-31). V. His feeding of four thousand men, with seven loaves and a few little fishes (Mat 15:32-39).

15:5 vowed to give to God: Such a gift was likely donated at the Temple (see Mark 7:11; see also Prov 28:24) but functioned as a way to dodge financial responsibility for one’s parents.
