Ezekiel 35 and 36 are the finishing of a circle. God does not like the Edomites for their treatment of God’s people and the way they disrespected Him. Hence, Edomites where destroyed. So Israel was being reestablished in the land that was promised. God reminds His people that their slavery, exile and persecution from human hands occurred because Israel had been disobedient to God and worshiped idols and many other despicable acts. Both the destruction and the reconstruction was ordained by the Lord. So He allows Israel to rise, fall low and rise again, destroying and rebuilding nations to reiterate "Then they will know I am Lord." I think we all have low places we've been or are in but I remember that the Lord is here to lift me up, support me and show me a fertile valley ... as long as I'm not putting idols between us.
