The Bible has the worst legal advice ever.
If a man files a lawsuit against you for your shirt give them your cloak as well.
I tried to live by it during my divorce and lost everything.
Epic bad legal advice.

I am going to be honest. I was not expecting so many responses!
So I am going to share the ones that got me the most.

1. Ecclesiastes 1:2
   "Meaningless! Meaningless!"
   Says the Teacher.
   "Utterly meaningless!
   Everything is meaningless."
   This one surprised me, just the sheer pessimism and nihilism behind it. I found several quotes and passages like this in Ecclesiastes.

2. Isaiah 45:7
   "I form the light, and create darkness: I make peace, and create evil: I, the Lord, do all these things."
   God straight up admits to being the creator of all bad things? I thought Christains always said Satan was the creator of all bad things. But this passage literally has God taking all the credit!

3. "If anyone comes to me and does not hate father and mother, wife and children, brothers and sisters - yes, even their own life - such a person cannot be my disciple."
   This came straight from the J man's mouth. I was raised in catholic schools. I was told that Jesus preached love and acceptance. But this? This is the exact opposite! He is straight up saying he won't take anyone unless they're a salty ass bitch!

4. Matthew 10:34
   "Do not suppose that I have come to bring peace to the earth. I did not come to bring peace, but a sword."
   Again from Jesus, holy shit! He straight up looking for a war here! This seems opposite of what I was told about this 'holy' figure.

5. 1 Kings 22:19-22
   19 Micaiah continued, “Therefore hear the word of the LORD: I saw the LORD sitting on his throne with all the multitudes of heaven standing around him on his right and on his left. 20 And the LORD said, ‘Who will entice Ahab into attacking Ramoth Gilead and going to his death there?’
   “One suggested this, and another that. 21 Finally, a spirit came forward, stood before the LORD and said, ‘I will entice him.’
   22 “‘By what means?’ the LORD asked.
   “‘I will go out and be a deceiving spirit in the mouths of all his prophets,’ he said.
   “‘You will succeed in enticing him,’ said the LORD. ‘Go and do it.’
   ... the fuck? This is God, sending an angel to a prophet, to deceive a man and trick/tempt him into starting a war! This is the shit we where taught that The Devil did! Not God! This is a pretty evil thing to do!

I am an atheist, and I am an atheist partially because I read parts of the bible. I could put so many more things here. But this is the stuff that REALLY got to me.
I was twelve when I started reading the bible. I wanted to deepen my faith and my connection to God. But this is the shit I found. Not going to lie, I had a crisis of faith for a good two years. But now I don't believe in this nonsense; and funnily enough, it's mainly because I read the book.

I didn't come across this paasage on my own but saw it listed on a website.

Ezekiel 23:20 (English Standard Version - ESV). "and lusted after her lovers there, whose members were like those of donkeys, and whose issue was like that of horses."

The New Living Translation version is even more graphic: "She lusted after lovers with genitals as large as a donkey’s and emissions like those of a horse."

I never saw this much bible study in a seminary

If you're wanting weird bible passages then, imo, all you need do is start at Line 1, page 1 and work your way through the whole bible.
There are, quite literally, thousands of them to be found like, for example,

1. God makes Adam from the dust of the Earth but needs to take a bone from Adam to make woman,
2. God creates everything with just a mere word and yet the Believers will tell you that god does not exist in a corporeal form, therefore God could NOT utter a single word even a sound since God was without Vocal Chords, lungs, tongue, mouth, etc, etc,
3. the Great and Mythical Jesus came upon a fig tree, Jesus was hungry but the Fig tree bore no fruit so he cursed it,
4. Moses raised his staff and the waters of the Red Sea parted until the Hebrews had ALL crossed via the wet and very soggy sea bed, then God caused the waters to flood back in and drowned the pursuing Egyptians, horses and all, really nice, cruel, sadistic move there God imo.

When god commanded to slaughter everyone in a city men women and children, pure evil

Here's my favorite passage from the wonderful book, "Animal Dreams" by Barbara Kingsolver. Naturally, it's about sex.

"He leaned over and I took his head in my hands and gave him the kiss I'd been thinking about for the last two hours. It lasted a good long while. He twisted his finger gently through my hair at the base of my skull and held on tight, and my breath stopped while he laid down a track of small kisses from my earlobe to my collarbone. We lay back on the grass and I rolled against him, looking down into his eyes. They were dark brown, a color with depth to it, like stained glass.

"Just being held felt unbelievably good, the long drink I'd been dying for. For a second I hugged back as tightly as I could. Something inside his buttoned shirt pocket made a crackling, cellophane sound. I raised up and poked it with my finger. "If you've got a condom in your pocket, Lloyd, this is my lucky day."

"He did. It was."

A lifelong skeptic, I never bothered reading the Bible.

In elementary school, I scoffed at ridiculous Bible stories. Realized the Bible is just a book of stories or fables written by men. Like Grimm's Fairy Tales.

ha ok you know most of that OT stuff is surely not meant to be taken literally?

If I remember correctly, it was Lot whose daughters got him drunk and had sex with him. Then both daughters had children, whose father was also their grandfather.

Ezekiel 23:20: "There she lusted after her lovers, whose genitals were like those of donkeys and whose emission was like that of horses."

Balaam’s Donkey
Numbers 22:21-39
