'Flattering' in the Bible

for such people do not serve our Lord Christ but their own appetites. They deceive the hearts of the unsuspecting with smooth talk and flattering words.

For we never used flattering speech, as you know, or had greedy motives—God is our witness—

These people are discontented grumblers, walking according to their desires; their mouths utter arrogant words, flattering people for their own advantage.
