‘13I placed my bow in the cloud... 16The bow being in the cloud, I … shall remember the perpetual pact of God.’
17God told Noah: ‘This is the sign of the covenant that I established between me and all the creatures of the earth.’”
Let’s do the grammatical analysis of verses 12, 13 and 16. The use of the first person in verse 16 implies that the God who speaks is split into a second God who, within the speech of the first God, speaks of His pact. The first God, of whom the rainbow is the most beautiful expression, is the sun-God. The second can only be the Egyptian living God: the pharaoh Akhenaten. He wrote those ver-es identifying with the sun-God Aten, of which he is the earthly incarnation.
The fact that God allies with all creatures shows He is Universalist and suggests the abandonment of blood sacrifice; it is not the same God as that of Genesis 15 and Genesis 17.
