John Trapp on Proverbs 6:18

Verſ. 18 An heart that deviſeth wicked imaginations] This is the old Beldame, the Mother of all the foregoing and following miſchiefs; and is therefore fitly ſet in the midſt of the ſeven, as having an influence into all. From the eies, the Wiſe-man deſcends to the mouth, from the mouth, to the hands, from the hands, to the heart, from thence to the feet, and ſo takes the parts in order as they ſtand: But as for the heart, it transfuſeth its venome into all the reſt, and may ſay to them all, as the heart of Apollodorus the Tyrant ſeemed to ſay to him, who dreamed one night that hee was fleaed by the Scythians, and boiled in a Caldron, and that his heart ſpake to him out of the kettle, [non-Latin text not transcribed]. It is I that have drawn thee to all this. Thoſe in Hell cry ſo doubtleſs.

Feet that bee ſwift] As if they ſhould come too late. This is a foul abuſe of the locomotive faculty given us by God for better purpoſe, that wee ſhould bee ſwift to hear, run to and fro to encreaſe knowledge, Dan. 12. walk in the way that is called holy, go from ſtrength to strength, taking long ſtrides towards Heaven, Pſal. 84.7. Thoſe then that walk in a contrary road, and make all poſſible haſte to heap up ſin upon ſin, muſt needs be abominated and accurſed of God.
