47 say to the forest of the Negeb, Hear the word of the Lord: Thus says the Lord GOD, Behold, I will kindle a fire in you, and it shall devour every green tree in you and every dry tree; the blazing flame shall not be quenched, and all faces from south to north shall be scorched by it.

Matthew Henry's Commentary on Ezekiel 20:47

Commentary on Ezekiel 20:45-49

(Read Ezekiel 20:45-49)

Judah and Jerusalem had been full of people, as a forest of trees, but empty of fruit. God's word prophesies against those who bring not forth the fruits of righteousness. When He will ruin a nation, who or what can save it? The plainest truths were as parables to the people. It is common for those who will not be wrought upon by the word, to blame it.
