John Trapp on Matthew 15:31

Verse 31. They glorified the God of Israel] They saw God in those miraculous cures, and gave him his due praise. He is content that we should have the comfort of his benefits, so he may [illegible: 1 word] the glory of them; that's all the rent and return he looks for. All the [illegible: 1 word] Christ required for his cures was, Go and tell what God [illegible: 2 words] for thee, Go shew thy self to the Priest and offer, &c. But we, insteed of being temples of Gods praise, become many times graves of his benefits. This made good David so oft to put the thorn to his breast, Psal. 103. 1,2,3. and King Alphonsus not so much to wonder at his Courtiers ingratitude to him, as at his own to God.
