I can quote it if I need to, but you related the Azalel to Satan.
In Lev. xvi. the single allusion to Azazel is as follows: On the tenth day of Tishri (see Atonement Day) the high priest, after first performing the prescribed sacrifices for himself and his family, presented the victims for the sins of the people. These were a ram for a burnt offering, and two young goats for a sin-offering. Having brought the goats before Yhwh at the door of the tabernacle, he cast lots for them, the one lot "for Yhwh" and the other "for Azazel." The goat that fell to Yhwh was slain as a sin-offering for the people. But the goat of Azazel (now usually known as the "scapegoat") was made the subject of a more striking ceremony. The high priest laid his hands upon its head and confessed over it the sins of the people. Then the victim was handed over to a man standing ready for the purpose, and, laden as it was with these imputed sins, it was "led forth to an isolated region," and then let go in the wilderness. (Jewish Encyclopedia/ Azazel)
The Azalel was released in an uninhabited place.
Aaron shall lay both his hands on the head of the live goat, confess over it all the iniquities of the children of Israel, and all their transgressions concerning all their sins, putting them on the head of the goat and shall send it away into the wilderness by the hand of a suitable man.
The goat shall bear on itself all their iniquities to an uninhabited land and he shall release the goat in the wilderness.
(Leviticus 16:21-22 NKJV)
The ultimate uninhabited place is the grave.
