Ezekiel 21:2

Son of man, set thy face toward Jerusalem,.... Which shows that this city was meant by "the south", Ezekiel 20:46:

and drop thy word toward the holy places; which also are meant by the south in the passage referred to, even the holy land, holy city, and holy temple; or the temple itself is only meant, with the courts adjoining to it; or as consisting of three parts, as Kimchi, the porch, the temple, and the oracle; or the outward court, the holy place, and the holy of holies; and it may respect all other places for sacred worship, as their synagogues, both in city and country; which were not to be spared any more than the temple, nor were they, Psalms 74:7. Jarchi thinks that the destruction both of the first and second temple is here intended; and which sense Kimchi also mentions.

And prophesy against the land of Israel: by which it appears that this is intended by the "forest of the south field": even the numerous inhabitants of it in general, as well as the city of Jerusalem,
