I think to lie is to move away from HaShem. The seal of HaKodosh Boruch Hu is emes. The absolute truth. Any step towards falsehood his moving away from HaShem. That’s why it is the only aveira that says ???? – distance yourself from it.
We learned in Tanach about the spirit of Navos, who suggested to HaShem that he become a ??? ??? – a consciousness of falsehood in the mouths of the prophets. HaShem told him ??, go out, (get out of here) out of the ????? of the proximity of HaShem’s presence. It was an important job, however it cannot be in the ?????, closeness of HaShem.
