REV 3:9

9 And did not make hakhchashah [(denial)] of ha-Shem of me. Hinei, I may make some of the Shul of the Adversary, the ones declaring themselves to be Bnei Brit, and are not [of the Brit Chadasha] but speak sheker; hinei, I will make them come and prostrate themselves before your feet and then they will have da'as that I have ahavah for you.
