What does Ezekiel 3:17 mean?

So the Spirit lifted me up, and took me away; and I went in bitterness, in the heat of my spirit; and Yahweh’s hand was strong on me.

Then I came to them of the captivity at Tel Aviv, that lived by the river Chebar, and to where they lived; and I sat there overwhelmed among them seven days.

At the end of seven days, Yahweh’s word came to me, saying,

When I tell the wicked, ‘You will surely die;’ and you give him no warning, nor speak to warn the wicked from his wicked way, to save his life; the same wicked man will die in his iniquity; but I will require his blood at your hand.

Yet if you warn the wicked, and he doesn’t turn from his wickedness, nor from his wicked way, he will die in his iniquity; but you have delivered your soul.”

“Again, when a righteous man turns from his righteousness, and commits iniquity, and I lay a stumbling block before him, he will die. Because you have not given him warning, he will die in his sin, and his righteous deeds which he has done will not be remembered; but I will require his blood at your hand.
