Jews do Satan’s work — they are Satan’s very own synagogue and children:

“I will make them of the synagogue of Satan, which say they are Jews, and are not, but do lie” Revelation 3:9

Jews do what their own father (the devil) does: lie and murder:

“Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.” John 8:44
