Jeremiah 9:5

Jer 9:5 And they will deceive every one his neighbour, and will not speak the truth: they have taught their tongue to speak lies, [and] weary themselves to commit iniquity.

Ver. 5. They have taught their tongues to speak lies. ] They are artists at it, and can tack one lie to another very handsomely. Psa 119:69 See Trapp on " Psa 119:69 "
