'Dealt' in the Bible

“Surely, as a wife treacherously (unfaithfully) leaves her husband,So you have dealt treacherously with Me,O house of Israel,” says the Lord.

“For the house of Israel and the house of JudahHave dealt very treacherously (faithlessly) with Me,” declares the Lord.

For the shepherds [of the people] have become [like brutes,] irrational and stupid,And have not searched for the Lord or asked about Him or realized their need for Him;Therefore they have not been wise and have not prospered,And all their flocks are scattered.

“For even your [tribal] brothers and the household of your father,Even they have dealt treacherously (unfaithfully) with you;Indeed they are [like a pack of hounds] howling after you.Do not believe them, although they may say kind words and promise you good things.”

that you have deceived yourselves; for you sent me to the Lord your God, saying, “Pray for us to the Lord our God; and whatever the Lord our God says, declare it to us and we will do it.”
