What do you think Jesus is citing in Matthew 19:4?
4 "Haven't you read," he replied, "that at the beginning the Creator 'made them male and female,'..."
Do you plead open New Testament ignorance?
I don't care what he was or wasn't quoting. Jesus is not relevent to the the Mosaic law. Mark and Matthew are not part of the Torah. Neither is Kings for that matter.
The Torah is Genesis, Exodus, Leviticus, Numbers and Deuteronomy. That’s it. That’s all there is.
