'Falsehood' in the Bible

Jesus saw Nathanael coming toward Him, and said of him, “Here is an Israelite indeed [a true descendant of Jacob], in whom there is no guile nor deceit nor duplicity!”

He who speaks on his own accord seeks glory and honor for himself. But He who seeks the glory and the honor of the One who sent Him, He is true, and there is no unrighteousness or deception in Him.

You are of your father the devil, and it is your will to practice the desires [which are characteristic] of your father. He was a murderer from the beginning, and does not stand in the truth because there is no truth in him. When he lies, he speaks what is natural to him, for he is a liar and the father of lies and half-truths.

But [as you might say] if through my lie God’s truth was magnified and abounded to His glory, why am I still being judged as a sinner?

As for you, the anointing [the special gift, the preparation] which you received from Him remains [permanently] in you, and you have no need for anyone to teach you. But just as His anointing teaches you [giving you insight through the presence of the Holy Spirit] about all things, and is true and is not a lie, and just as His anointing has taught you, you must remain in Him [being rooted in Him, knit to Him].

and nothing that defiles or profanes or is unwashed will ever enter it, nor anyone who practices abominations [detestable, morally repugnant things] and lying, but only those [will be admitted] whose names have been written in the Lamb’s Book of Life.

Outside are the dogs [the godless, the impure, those of low moral character] and the sorcerers [with their intoxicating drugs, and magic arts], and the immoral persons [the perverted, the molesters, and the adulterers], and the murderers, and the idolaters, and everyone who loves and practices lying (deception, cheating).
