'Dealt' in the Bible

"Moreover, you also know what Joab the son of Zeruiah did to me when he dealt with the two commanders of the armies of Israel, to Abner son of Ner and to Amasa son of Jether, and he murdered them and put the blood of war in [a time of] peace. He put the blood of war on the leather belt that was on his waist and on the sandals which were on his feet.

and if they shall take it to heart in the land whither they were carried captive, and repent, and make supplication unto thee in the land of them that carried them captive, saying, We have sinned, and have done iniquity, we have dealt perversely;

And Omri did that which was evil in the sight of Jehovah, and dealt wickedly above all that were before him.
