without any reason for that.
The OT uses the divine name. When the NT quotes a verse from the OT that uses the divine name, it is also reasonable to conclude that the original Bible writers of the NT also used the divine name in the NT. By the same token it is also axiomatic that Jehovah is God and any verse in the Bible that implies or infers the true God is referring to Jehovah. It is also interesting that Bible translators of the OT also substitute the divine name with titles.
