As pointed out by Rabbi Y. Adlerstein:
… Bekolo Tishme’un/ “you shall hearken to His voice.” This is accompanied by a picture of Rav Ovadia, or Rav Chaim, or yibadel le-chaim, Rav Gershon. (The poster designers seem completely oblivious to the blasphemous nature of the ads, which replace HKBH with basar v’dam. [See the only two places in Tanach where the phrase appears: Devarim 13:5, and Tehillim 95:7.])
See for yourself…
