'Flatter' in the Bible

For there is no faithfulness in their mouth; their inward part is very wickedness; their throat is an open sepulchre; they flatter with their tongue.

People lie to one another; they flatter and deceive.

They say, "We speak persuasively; we know how to flatter and boast. Who is our master?"

Nevertheless they did flatter him with their mouth, and they lied unto him with their tongues.
