Amraphel is a name that appears in the Bible, specifically in the book of Genesis. It refers to a king who ruled over a place called Shinar, which is believed to be the ancient city of Babylon.
Now, you might be wondering what a king is. Well, just like you have a teacher who is in charge of your classroom, a king is someone who is in charge of a whole bunch of people and a big piece of land called a kingdom.
Amraphel was a very powerful king who ruled over many other kings and their kingdoms. But he wasn't always a nice guy. He and his allies would go to war with other kings and try to take over their kingdoms.
One time, Amraphel and his allies went to war against some other kings who had rebelled against them. They won the war and took many people as prisoners.
But there was one person they couldn't take down: Abram. Abram was a good guy who believed in God and didn't want to fight. So he made a deal with Amraphel and his allies to let him and his people go free. And they did.
So basically, Amraphel was a king who ruled over a part of the world a long time ago, and he was not always a nice guy. But he did let Abram and his people go free when they didn't want to fight.
