What does Ezekiel 20:45 mean?

You will know that I am Yahweh when I bring you into the land of Israel, into the country which I swore to give to your fathers.

There you will remember your ways, and all your deeds in which you have polluted yourselves. Then you will loathe yourselves in your own sight for all your evils that you have committed.

You will know that I am Yahweh, when I have dealt with you for my name’s sake, not according to your evil ways, nor according to your corrupt doings, you house of Israel,” says the Lord Yahweh.’”

“Son of man, set your face toward the south, and preach toward the south, and prophesy against the forest of the field in the South.

Tell the forest of the South, ‘Hear Yahweh’s word: Thus says the Lord Yahweh, “Behold, I will kindle a fire in you, and it will devour every green tree in you, and every dry tree. The burning flame will not be quenched, and all faces from the south to the north will be burned by it.

All flesh will see that I, Yahweh, have kindled it. It will not be quenched.”’”
