The Gemara in Sanhedrin that I came across today quotes a Baraisa that learns out from the Pasuk which reads “do not place an evildoer as a witness, do not place a thief as a witness.” The Baraisa ends by saying the words evildoer and thief refer to robbers and those who abuse oaths. 

The Drasha here is that the word that the Gemara uses for thief is “חמס” Hamas!!

The Drasha of the Baraisa is that When the Torah uses the word Hamas it is referring to robbers and people who lie and break their promises. Individuals that can never be trusted! 

Pretty wild actually.
