Seems the speaker is just saying the other person should not be deceitful.

I found a link from Google (remember Google isn't totally trustworthy)that may be useful.

However, a second type of shame is introduced. "False shame" is claimed to be similar to "legitimate shame" in terms of humiliation experienced plus the fear of exposure and abandonment. It has no beginning point, no remedy, and is connected with "how we perceive ourselves at the core of our being" (flawed and defective) rather than with our actual sin. "Shame is the sense of feeling flawed, defective and unacceptable as a person" (37). The author insists that no one has escaped this "false shame," and she proposes a "contagious," cyclical pattern wherein people shame one another and perpetuate "false shame" in others (37-46). She teaches that Satan originates it, because "he knows the areas that are especially painful to each person and he reminds us of them over and over" (10). Like Bradshaw, this author attributes the development of "false shame" to early childhood experiences, including parental abuse and the sense of being different from others (14-15). She believes that "one’s core beliefs about one’s self are usually in place before adolescence" (17). Because such "core beliefs" are based on a variety of sources, even persons from "warm, functional" homes may suffer from the impact of shame (17).

I hope this is useful. Sounds okay.
