Psalms 5:9

5:9 For they do not speak the truth;

their stomachs are like the place of destruction,

their throats like an open grave,

their tongues like a steep slope leading into it.

Psalms 12:2

12:2 People lie to one another;

they flatter and deceive.

Psalms 55:21

55:21 His words are as smooth as butter,

but he harbors animosity in his heart.

His words seem softer than oil,

but they are really like sharp swords.

Proverbs 29:5

29:5 The one who flatters his neighbor

spreads a net for his steps.

Isaiah 59:13-15

59:13 We have rebelled and tried to deceive the Lord;

we turned back from following our God.

We stir up oppression and rebellion;

we tell lies we concocted in our minds.

59:14 Justice is driven back;

godliness stands far off.

Indeed, honesty stumbles in the city square

and morality is not even able to enter.

59:15 Honesty has disappeared;

the one who tries to avoid evil is robbed.

The Lord watches and is displeased,

for there is no justice.

Jeremiah 9:3-5

The Lord Laments That He Has No Choice But to Judge Them

9:3 The Lord says,

“These people are like soldiers who have readied their bows.

Their tongues are always ready to shoot out lies.

They have become powerful in the land,

but they have not done so by honest means.

Indeed, they do one evil thing after another

and do not pay attention to me.

9:4 Everyone must be on his guard around his friends.

He must not even trust any of his relatives.

For every one of them will find some way to cheat him.

And all of his friends will tell lies about him.

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.

Ezekiel 33:30-31

33:30 “But as for you, son of man, your people (who are talking about you by the walls and at the doors of the houses) say to one another, ‘Come hear the word that comes from the Lord.’ 33:31 They come to you in crowds, and they sit in front of you as my people. They hear your words, but do not obey them. For they talk lustfully, and their heart is set on their own advantage.
