No verse stands on its own - it must be compared to the spiritual of other like verses to correctly understand it.
You are just perceiving the one verse to be complete within itself, which it is not, and thereby, you violate the rule of 2 Pe 1:20.
[2Pe 1:20 KJV] 20 Knowing this first, that no prophecy of the scripture is of any private interpretation.
[1Co 2:13 KJV] 13 Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual.
