In the Bible, God comes in 6 names.
This was done to refer these name to depict the era or period of times of God story.
Yahweh was 1st name of God from Chapter 1 Genesis.
Then in Chapter 4, Moses time God was named Jehovah...
Then later God was named Elijah, Elohim, Lord of Host, Emanuel.
Bible was stopped written about AD 150. In AD 425, Prophet Mohammed found the Jesus brother James descendant, the Ebonite tribe in the Minor Asia, and get to know the story of Jesus.
The tribe probably have created a new name their God called Allah, to avoid found and be killed by the Romans Empire who still hunt and want killed them to extinction 斩草除根 ....
Like the BE was referred to 1066 to 1940s of evil AMDK British.
Qing Dynasty was in 1700 to 1900 of China period...
Hope this help...
