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"}
