John Trapp on Proverbs 6:19

Verſ. 19. A falſe witneſs that ſpeaketh lies] Heb. That blows abroad lies, as with a pair of bellows, that vents them boldly and freely in open Court, in the face of the Countrey. Theſe Knights of the Poſt can lend an oath for a need, as they did Jeſabel againſt Naboth, and like thoſe in the hiſtory, will not ſtick to ſwear that their friend or foe was at Rome and Interamna both at once. God oft thundereth againſt ſuch, to ſhew his utter hatred of them: and hath, threatned that the winged flying-book that is full of curſes within and without, ſhall overtake them ere they get home, and ſhall reſt in the midſt of their houſes, to conſume them with the timber thereof, and the ſtones thereof, Zach. 5.4.

And him that ſoweth diſcord] See the Notes on verſ. 14. & 16. Unity among brethren is fitly compared to a Cable-Rope, which will not eaſily break but if once cut aſunder, its hard to tye a knot upon it; what ill officers then are Breed-bates, and boutefeus?
