John Trapp on Matthew 15:14

Verse 14. Let them alone] A dreadfull doom; like that, Hos. 4. 14. I will not punish your daughters, when they commit whoredom, &c. No so great punishment as not to be punished. And vers. 17. of that same Chapter, Ephraim is joyned to idols, let him alone, q. d. He hath made a match with mischief, he shall have his belly-full of it. Never was Jerusalems condition so desperate, as when God said unto her, My fury shall depart from thee, I will be quiet, and no more angry, Ezek. 16. 42. A man is ever and anon medling with his fruit-trees, paring and pruning, &c. but for his oaks, and other trees of the forrest, he lets them alone, till he comes, once for all, with his axe to fell them. Both shall fall into the ditch] Though the blinde guides fall undermost, and have the worst of it.
