Between the red-rusty caverns of Idumaea and the dun-colored [grey] plateau of Aram; between the limp Jordan basin and the Mediterranean; from the seven-faceted [the challenge is to make a sensible connection to the idea of  "...1st millennium CE Jewish scholars developed an elaborate system of Seven Heavens"], dense and low (hanging) heavens, to the rolling land of yellow groves, yellow dunes and yellow fields, stretches lazily Eretz Israel, which Jehovah gave to his favored people to occupy. [Eretz Israel, which Jehovah gave as a possession to his favored people, lazily stretched between the rust-colored caverns of Idumaea and the gray plateau of Aram, between the fertile Jordan basin and the Mediterranean, from the dense, low heavens to the rolling land of yellow groves, yellow caverns and yellow fields under the plow.]

Između rđastih pešteri Idumeje i sure aramske visoravni, između mlitavog sliva Jordana i Sredozemlja, od sedmolikog, gustog i niskog neba do grbavog tla žutih gajeva, žutih peščara i žutih oranica, prostire se leno Erek Jisrael, koji je Jahve dao u pritežanje svom narodu-mezimcu.

Zwischen den rot-rostigen Höhlen von Idumaea und der dunfarbenen Hochebene von Aram; zwischen dem schlaffen Flussbett des Jordan und dem Mittelmeer; aus den dichten und tief hängenden Sieben Himmeln zu den rollenden Hügeln und gelben Hainen, gelben Dünen und gelben Felder, erstreckt sich träge Eretz Israel, das Jehova seinem bevorzugten Volk zu Beherrschung (über)gab.

Vladimir D. Janković:

Those rust-colored caverns first. Yes, the standard translation for the word pešter is cave, or cavern, but when did you see a rust-coloured (rđasta) cavern? It’s always dark in a cave, so any red, rusty nuance just cannot dominate in such places... Altough, it’s Idumaea, not Western or Southwestern Serbia, for instance, where caves are deep gray, black-green, echoing with sounds of water.

So, the rust-colored pešters should be rust-colored ravines; yes, these are ravines, they can be seen from outside, they are not hidden from the Sun.

Dun-colored... Great solution. It evokes a desert (dune). Let’s leave it as it is.

* * *

Limp Jordan basin... Well, what about bedridden Jordan basin? Pure madness.

* * *

Why not seven-faceted, pregnant, low skies? There is some Alabamian ambiance in it, what do you say? With Skynard plane falling from those pregnant, low skies?

* * *

I would put dunes, as a connection with dun-colored.

* * *

Stretches lazily – good.

…which Jehovah gave to his favored people to control/rule. 
It could be like this: ... which Jehovah bestowed to his beloved people to govern.
