It seems that was an oral tradition of parables and stories in Aramaic that Jesus collected prior to any ministry. He made use of these. Then there was a several decade long period where his teachings were handed over to others, modified, added to, etc. So the chance of finding out what Jesus actually said is very slim. All that we have is compilation from multiple sources. One might come up with a number of possible ideas how this compilation came about. But actually knowing how can never be fully known.
