What does Ezekiel 33:19 mean?

None of his sins that he has committed will be remembered against him. He has done that which is lawful and right. He will surely live.

“‘Yet the children of your people say, “The way of the Lord is not fair;” but as for them, their way is not fair.

When the righteous turns from his righteousness, and commits iniquity, he will even die therein.

Yet you say, “The way of the Lord is not fair.” House of Israel, I will judge every one of you after his ways.’”

In the twelfth year of our captivity, in the tenth month, in the fifth day of the month, one who had escaped out of Jerusalem came to me, saying, “The city has been defeated!”

Now Yahweh’s hand had been on me in the evening, before he who had escaped came; and he had opened my mouth, until he came to me in the morning; and my mouth was opened, and I was no longer mute.
