John Trapp on Jeremiah 9:3

Ver. 3. And they bend their tongues like their bow for lyes] To the impeaching of others in their name, ſtate and life. I read that in Italy at this day they have a pocket-ſtone-bow, which held under a cloak ſhoots needles with violence to pierce a mans body, yet leaveth a wound ſcarce diſcernable. Lo ſuch is an evil tongue,Il. Mercurio Italico. and ſuch miſchief it may do a man.

But they are not valiant for the truth] Truth is no part of their profeſſion: and courage in a good cauſe they have none. Of the moſt we may ſay as of Harts and Stags, they have great hornes, but to little purpoſe;Plutarch. or as Themiſtocles ſaid of the Eretrians, that they were like the ſword-fiſh which hath a ſword indeed, but not a heart to make uſe of it.

And they know not me ſaith the Lord] The low apprehenſions men have of God, make their hearts work ſo poorly after him, Pſal. 9.10.
