Psalms 5:9

¹³“Their throat is an open tomb. With their tongues they have used deceit.”“The poison of vipers is under their lips.”

³“They bend their tongue, as their bow, for falsehood. They have grown strong in the land, but not for truth; for they proceed from evil to evil, and they don’t know me,” says the LORD. ⁴“Everyone beware of his neighbor, and don’t trust in any brother; for every brother will utterly supplant, and every neighbor will go around like a slanderer. ⁵Friends deceive each other, and will not speak the truth. They have taught their tongue to speak lies. They weary themselves committing iniquity. ⁶Your habitation is in the middle of deceit. Through deceit, they refuse to know me,” says the LORD.

⁴They fully intend to throw him down from his lofty place. They delight in lies. They bless with their mouth, but they curse inwardly. Selah.

¹²Her rich men are full of violence, her inhabitants speak lies, and their tongue is deceitful in their speech.

⁵A man who flatters his neighbor spreads a net for his feet.

²Your tongue plots destruction, like a sharp razor, working deceitfully.

⁴⁴Woe to you, scribes and Pharisees, hypocrites! For you are like hidden graves, and the men who walk over them don’t know it.”

⁶Behold, you desire truth in the inward parts. You teach me wisdom in the inmost place.

⁶They plot injustice, saying, “We have made a perfect plan!” Surely man’s mind and heart are cunning.

⁹The heart is deceitful above all things and it is exceedingly corrupt. Who can know it?
