"You are my witness (Hebrew: עד OD), saith Iod Hei Vav Hei, and my servant (Hebrew: עבד OBD) whom I have chosen: that ye may know (Da'ath) and believe me, that these are the faces of your Binah: before me "El" (Chesed) was not formed, neither shall he (Chesed) become after me (Binah). I, even I, am Iod Hei Vav Hei; and AIN as part of me is one savior." - Isaiah 43: 10, 11
