Psalms 50:10

For every beast of the forest is mine, and the cattle upon a thousand hills.
8

I will not reprove thee for thy sacrifices or thy burnt offerings, to have been continually before me.

9

I will take no bullock out of thy house, nor he goats out of thy folds.

10

For every beast of the forest is mine, and the cattle upon a thousand hills.

11

I know all the fowls of the mountains: and the wild beasts of the field are mine.

12

If I were hungry, I would not tell thee: for the world is mine, and the fulness thereof.

Counter-Arguments

The strongest case that this verse does not belong in this theme.

Symbolic Millennium

The verse explicitly states "a thousand hills" as a quantity of hills, not as a symbolic representation of an indefinite period or a completeness of time. There is no contextual information in this verse to suggest a symbolic meaning for the number "thousand" in relation to a millennium.
