'Flattering' in the Bible

They speak falseness {to each other}. [With] flattering lips, [with] {a double heart} they speak.

May Yahweh cut off all flattering lips, [the] tongue speaking great boasts--

A tongue of deceit hates its victim, and a flattering mouth makes ruin.

For [there] will not be any longer {any false vision} or flattering divination in the midst of the house of Israel.
