'Flattering' in the Bible

For such men are slaves, not of our Lord Christ but of their own appetites; and by their smooth and flattering speech they deceive the hearts of the unsuspecting.

For we never came with flattering speech, as you know, nor with a pretext for greed—God is witness—

These are grumblers, finding fault, following after their own lusts; they speak arrogantly, flattering people for the sake of gaining an advantage.
