John Trapp on Jeremiah 4:14

Ver. 14. O Jeruſalem, waſh thine heart from wickedneſſe] Which defileth it worſe then any leproſy,Fruſtra ſunt lavamenta, ubi nulla eſt innocentia. Oecol. or jakes, doth the body, Mar. 7.19, 20, 23. Thy hands thou often waſheſt (and other outward parts; placeing therein no ſmall religion) thou canſt not waſh them in innocency; waſh them therefore in tears: and when thou haſt ſo done, cry to God with Auſtin, Lava lachrymas meas Domine: ipſae enim lachrymae ſunt lacrymabiles; Waſh my very tears, Lord; for they are lamentable ones. Beg of him to bathe thy ſoul in the blood of his Son, to waſh thee throughly from thine iniquity, and to cleanſe thee from thy ſin, Pſal. 51.2.

That thou maiſt be ſaved] i. e. Have ſafety here, and ſalvation hereafter.

Hic mora cogitationis redarguitur & ejus adlubeſcentia. Oecol. How long ſhall thy vain thoughts lodge within thee?] Heb. in the midſt of thee, in the very heart of thee? Creep in they will: but why ſhould they lodge there? why ſhould the Devil be at Inne with us? be any mans bed-fellow, as he is the angry mans, Epheſ. 4.26? David oft communed with his own heart, and his ſpirit made diligent ſearch for ſuch vagrants, Pſal. 77.6. Scopabam ſpiritum mem (ſo ſome render it) I ſwept out my ſpirit.Vulg. Carnal hearts are ſtews of unclean thoughts, ſlaughter-houſes of cruel and bloody thoughts, exchanges and ſhops of vain and vile thoughts, a very forge and mint of falſe Politick undermining thoughts, yea oft a little hell of confuſed and black imaginations. They had need therefore to be carefully cleanſed, and kept with all cuſtody. Grace beginnerh at the center, and from thence goeth to the circumference. God and Nature begin at the heart: Art begins with the face and outward lineaments; ſo doth Hypocriſy at outward paintings and expreſſions; it clenſeth the outſide of the cup and platter, when the inſide is full of ravening and wickedneſſe, Luke 11.39.
