John Trapp on Jeremiah 17:6

Ver. 6. For he ſhall be like the heath] Wild-myrice, that neither beareth fruit nor ſeed, and is good for little but to burn, or make beeſomes: See Heb. 6.8. Baſtard tamarisk ſome call it; others, Juniper.

But ſhall inhabit the parched places of the wilderneſſe] Such ſhall have no content or ſatisfaction. Confer Mat. 12.43. the unclean ſpirit caſt out, walks in dry places, &c. not but that dry and wet is all one with him: but it importeth his extream reſtleſneſſe.
