What does 2 Chronicles 28:11 mean?

The children of Israel carried away captive of their brothers two hundred thousand, women, sons, and daughters, and took also away much plunder from them, and brought the plunder to Samaria.

But a prophet of Yahweh was there, whose name was Oded; and he went out to meet the army that came to Samaria, and said to them, “Behold, because Yahweh, the God of your fathers, was angry with Judah, he has delivered them into your hand, and you have slain them in a rage which has reached up to heaven.

Now you intend to degrade the children of Judah and Jerusalem as male and female slaves for yourselves. Aren’t there even with you trespasses of your own against Yahweh your God?

Then some of the heads of the children of Ephraim, Azariah the son of Johanan, Berechiah the son of Meshillemoth, Jehizkiah the son of Shallum, and Amasa the son of Hadlai, stood up against those who came from the war,

and said to them, “You must not bring in the captives here, for you intend that which will bring on us a trespass against Yahweh, to add to our sins and to our guilt; for our guilt is great, and there is fierce wrath against Israel.”

So the armed men left the captives and the plunder before the princes and all the assembly.
