Revelation 3:9-10

"I will make those who are of the synagogue of Satan, who claim to be Jews though they are not, but are liars--I will make them come and fall down at your feet and acknowledge that I have loved you. Since you have kept my command to endure patiently, I will also keep you from the hour of trial that is going to come upon the whole world to test those who live on the earth."
