Psalms 52:3-4

52:3 You love evil more than good,

lies more than speaking the truth. (Selah)

52:4 You love to use all the words that destroy,

and the tongue that deceives.

Jeremiah 9:5

9:5 One friend deceives another

and no one tells the truth.

These people have trained themselves to tell lies.

They do wrong and are unable to repent.
