1 John 2:22
Who is a liar but he that denieth that Jesus is the Christ? He is antichrist, that denieth the Father and the Son.
44 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. 45 And because I tell you the truth, ye believe me not. 46 Which of you convinceth me of sin? And if I say the truth, why do ye not believe me? 47 He that is of God heareth Godís words: ye therefore hear them not, because ye are not of God. 48 Then answered the Jews...
1 Thessalonians 2:14b-15
for ye also have suffered like things of your own countrymen, even as they have of the Jews: 15 who both killed the Lord Jesus, and their own prophets, and have persecuted us; and they please not God, and are contrary to all men:
I know thy works, and tribulation, and poverty, (but thou art rich) and I know the blasphemy of them which say they are Jews, and are not, but are the synagogue of Satan.
Behold, I will make them of the synagogue of Satan, which say they are Jews, and are not, but do lie; behold, I will make them to come and worship before thy feet, and to know that I have loved thee.
