I'll give three types of such falsity, though the fault may be in the eyes of the beholder a rather than the minds of the authors:
(1) 1 Samuel 15:3
"Now go, attack the Amalekites and totally destroy all that belongs to them. Do not spare them; put to death men and women, children and infants, cattle and sheep, camels and donkeys.’”
Personally, I cannot understand how this command demonstrates the morality of God.

(2) 1 Timothy 2:12
"I do not permit a woman to teach or to assume authority over a man; she must be quiet."
Rather than outright error, I believe this to be a kind of guess, and so open to the possibility of being incorrect.
In other places Paul is fond of saying, "God does not..." Here, he says, "I do not..." So it's logical to assume he is giving his own opinion, and thus, such a premise is not immune to giving people the wrong impression that this is some kind of divine edict. There are other places where Paul makes it even more clear he is giving his own opinion on some subject in which he is unsure what God's opinion is.
I am of the opinion that Paul is mistaken. I've learned a great deal from women who have taught me.

(3) Matthew 26:26
"While they were eating, Jesus took bread, and when he had given thanks, he broke it and gave it to his disciples, saying, 'Take and eat; this is my body.'"
Rather than outright error, these words of Jesus are to me obviously ambiguous, and so open to misinterpretation. Did he mean this?
"...this [bread] is [like] my body...."
Or did he mean this?
"...this [bread] is [actually] my body...."
It is one source of contention between Catholics and some Protestants.
I haven't made up my mind what the intended meaning of Jesus' words are, and so I'm something of a Christian without a religion.
