You are from the Av of you, Hasatan [BERESHIS 3:4-5; TEHILLIM 58:4(3)], and the ta'avot of your Av you want to do, for that one was a rotze'ach from Bereshis, and he has not taken a stand in HaEmes, because HaEmes is not in him. When he speaks the sheker, he speaks naturally, because he is a shakran (liar) and the av of it. [Gn 3:4 2Ch 18:21; Ps 5:6; 12:2]
