2 Chronicles 25:10

Then Amaziah separated them
From his army, among whom they were incorporated and ranked, to wit,

the army that was come to him out of Ephraim;
which he had hired of the ten tribes, these he singled out:

to go home again;
to their own country:

wherefore their anger was greatly kindled against Judah, and they
returned home in great anger;
it being a great slight put upon them, and a reproach to them, to be thus dismissed, as they thought; and especially if they understood that it was because they were idolaters; and the rather as they might have hoped to have had their share in the plunder of the Edomites.
