Jeremías 9

Y cada cual se burlará de su propio hermano; y no hablarán jamás verdad, porque tienen avezada su lengua a la mentira; se afanaron en hacer mal.

Y cada uno engaña á su compañero, y no hablan verdad: enseñaron su lengua á hablar mentira, se ocupan de hacer perversamente.

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.

Friends deceive each other, and will not speak the truth. They have taught their tongue to speak lies. They weary themselves committing iniquity.
