Nobody really knows what Jesus actually said because he never wrote anything down. The only thing we know about him is what other people claimed he said; which is likely far from the truth IMO.
Jesus is said to have said things.
If Jesus was said to have written things there would be the same problem, how would you know that was true?
IOWs if you don't believe what He is said to have said, you won't believe what He is said to have written.
As far as if he was described to be exactly like Yahweh? When I look at how Jesus instructed his followers to treat their enemies (Luke 6:28) vs the way Yahweh instructed his followers to treat their enemies (Numbers 31:17) they appear to be polar opposites to me.
In the OT God was establishing Israel as His earthly Kingdom with Himself as King and was commanding His people as a King does, to protect His subjects from enemies who would cause them harm.
When it came to the way Israel was to treat the stranger and alien in their country, it was always to treat them well, but the establishing of the country and getting rid of the inhabitants of the land was a different question.
When Jesus came He came to establish a Kingdom not of this world and so war and killing was not necessary,,,,,,,,,,,that came later when Christians became political and wanting to set up an earthly Kingdom.
I believe it was Mark Twain who said
“men of war will worship a God of war, men of peace will worship a God of peace”
I believe men like Moses, Saul, and others in the Old Testament were men of war, so when they created a God, they created a God of war (Yahweh)
Later in the New Testament, men like Peter, Paul, and John were men of peace, so when they created a God they created a God of peace (Jesus).
But that's just the way I see it.
It was just the circumstances of the times and what God was doing. Moses actually is said to have been a very humble man (Numbers 12:3)
