Love thy neighbor

I actually have some theological commentary on that, if anyone is open to it. I just don't want to distract too much from the memery with serious religious talk if nobody wants it

Let’s hear it. I don’t wanna argue I just wanna hear your point

I'll reply in a few hours. I'm on mobile and at work

The God of the Old Testament (Jehovah), appears to be a vengeful god, but He's actually just delivering immediate consequences. One look at the way the Israelites actually behaved, and it becomes clear why Jehovah would treat them that way. These people were so distracted from their worship that while Moses was getting the 10 commandments FROM GOD HIMSELF, the Israelites, clergy and all, started a new religion!
The people that are front and center in the story of the Old Testament (whether or not it's a factual history) needed immediate consequences for their actions. That's why Mosaic Law requires an eye for an eye, or some kind of sacrifice to God to atone for every single sin.
A people that is on God's side, and gets treated like that—well, they're going to interpret and retell everything around them through the same lens.
If an Israelite gets blasted by God almost immediately, as a sudden and direct consequence for some sin, then the Egyptians will too.

Enter Jesus:
Christ's message was that He was the Son of God (different denominations debate on whether Christ was the Son, the Father incarnate, the Spirit of God in a fleshy body etc—Some believe that Christ was the physical manifestation of Jehovah, the OT god who required all those sacrifices), that He came to save mankind and usher in a new heavenly kingdom, and (this is specific to the Jewish audience) that He would fulfill the Law of Moses. Christ's suffering and death would be the final blood sacrifice. If God Himself offers the sacrifice to pay for sins, it would naturally be a perfect and complete sacrifice.
The fundamental theological shift from the Old to New Testament worlds is highlighted in Christ's Sermon on the Mount (Matthew 5), where He repeats the phrase "Ye have heard it has been said...", and issues a new law. The Law of Moses /was/ required, but no longer is. Christ is the last sacrifice, and He takes with Himself all of our sins (Isaiah 53:6).
...

Under the Law of Moses, consequences were immediate, and the Jewish people saw and wrote about the world that way. Christ updated the theology, added new laws, and gave His people a higher vision. It was no longer about immediate consequences. He wanted people to think about who they were as a person, more than what their immediate actions were. The parables are full of people whose actions have no consequences until the Kingdom comes. Matthew 19:23, for example is about what kind of person can make it in the world to come. Same for Matthew 18:3.
During this short, 3-year ministry, Jesus upended the long-standing religious tradition and replaced it with compassion, mercy, forgiveness, and turning the other cheek.
Without the context of the Old Testament, however, it would never be clear just how radically compassionate and empathetic Christ's actual teachings were.
Thanks for coming to my Ted Talk

I always thought Gods name in the OT was Yahweh.

That's one way to spell it. It's (יהוה) in Hebrew, or YHVH. The Hebrew letter for V is sometimes pronounced as an English "w".
From the Jewish Study Bible:
"YHVH was probably originally pronounced 'Yahweh,' but in Second Temple times, as an expression of reverence, Jews began to avoid uttering it, substituting 'adonai' [usually translated in English as 'The Lord'] and other surrogates. (As a reminder to [say 'adonai' instead of 'Yahweh'], in printed Hebrew Bibles the consonants are accompanied by the vowels of the surrogate words, leading to such hybrid English forms as Jehovah."
.
Jehovah is a combination of the Hebrew consonant-only YHVH and the vowels from "adonai".

Apparently, in some instances, it's not even proper to use a name to refer to God, and the term "Ha-Shem" is used, which literally means "the Name". This is the case in the Hebrew text of Exodus 20:7, the commandment not to take "The Name" in vain.

I had no idea about the hebrew spelling kinda neat actually
