Matthew 7:6

That which is holy; the holy flesh of the sacrifices.

Trample them; as things to them valueless.

Turn-and rend you; turn from the pearls in rage to attack the given, because he has offered them what they cannot eat. Dogs and swine represent selfish, quarrelsome, rapacious, and sensual men, whom it is often best to leave to themselves, lest our indiscreet labors be not only thrown away as regards them, but turn to our own injury. Scorners and scoffers should sometimes be let alone, lest, on being reproved, they become more injurious than they otherwise would be, to themselves and to others. Proverbs 9:7-8.
