'Swindler' in the Bible

So He asked him, “What is your name?” And he said, “Jacob.”

“But cursed be the swindler who has a male in his flock and vows it, but sacrifices a blemished animal to the Lord, for I am a great King,” says the Lord of hosts, “and My name is feared among the nations.”

But now I am writing you not to associate with anyone who claims to be a believer who is sexually immoral or greedy, an idolater or verbally abusive, a drunkard or a swindler. Do not even eat with such a person.
