Prophesy therefore concerning the land of Israel, and say to the mountains and to the hills, to the water-courses and to the valleys, Thus saith the Lord Jehovah: Behold, I have spoken in my jealousy and in my fury, because ye have borne the ignominy of the nations;
Ezekiel 36:4 therefore, ye mountains of Israel, hear the word of the Lord Jehovah. Thus saith the Lord Jehovah to the mountains and to the hills, to the water-courses and to the valleys, to the desolate wastes and to the cities that are forsaken, which are become a prey and a derision to the remnant of the nations that are round about,
Ezekiel 36:5 therefore thus saith the Lord Jehovah: Surely in the fire of my jealousy have I spoken against the remnant of the nations, and against the whole of Edom, which have appointed my land unto themselves for a possession with the joy of all [their] heart, with despite of soul, to plunder it by pillage.
Ezekiel 36:6 Prophesy therefore concerning the land of Israel, and say to the mountains and to the hills, to the water-courses and to the valleys, Thus saith the Lord Jehovah: Behold, I have spoken in my jealousy and in my fury, because ye have borne the ignominy of the nations;
Ezekiel 36:7 therefore thus saith the Lord Jehovah: I have lifted up my hand, [saying,] Verily the nations that are about you, they shall bear their shame.
Ezekiel 36:8 And ye mountains of Israel shall shoot forth your branches, and yield your fruit to my people Israel: for they are at hand to come.
The verse centers on "prophesy", "therefore", "concerning", "land", "israel", "mountains", "hills", and "water-courses". It is saying that the verse draws attention to "prophesy" and "therefore", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 5's "therefore thus saith the Lord Jehovah Surely..." into verse 7's "therefore thus saith the Lord Jehovah I...", so "prophesy" and "therefore" belong inside that flow. In Ezekiel context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "prophesy" and "therefore" with trust shaped by these words, not by a vague optimism outside the passage.
