When people lie or speak falsely in the Bible, it represents the "falsity of faith" and the resulting "evil of faith." This is what happens when people form their ideas based on bad information and incorrect assumptions. This leads to wrong ways of thinking and evil.

6706. The different kinds of neighbour - which a member of the Church ought to be thoroughly acquainted with if he is to know the true nature of charity - are determined by the good present in each individual. And since all good comes from the Lord, the Lord is in the highest sense and a supereminent degree the Neighbour and origin of the neighbour. From this it follows that a person is the neighbour in the measure Lord resides with him, since nobody receives the Lord, that is, the good which comes from Him, in the same way as another, no one person is therefore the neighbour in the same way as another. For all without exception in heaven and all without exception on earth differ from one another in good. Good is never exactly one and the same with any two people; variation is essential, in order that each kind of good may continue to exist by itself. But no one, not even an angel, can know all those variations, thus all the distinctions of the neighbour that are determined by the way the Lord is received, that is, the good coming from Him. One can know them in only an overall way, that is, know the general kinds of variation and some of the specific kinds of these. Nor does the Lord demand anything more of a member of the Church than that he should lead a life in keeping with what he knows.
