We will descend.
The way to our precious Canaan lies obviously downhill.

An end of uplift.

Downhill to the land of milk and honey.

The blood will soon be flowing faster than either, but we can't help that.

We can't help it if Canaan has blood in its veins, instead of pure milk and honey.
If it is a question of origins, the origin is always the same, whatever we say about it.
