The origin or the spirit of abortion can most likely be found several centuries ago in the culture of the the Moabite and Ammonite people. The people of Moab and Ammon worshiped the gods Chemosh(god of the Moabites), and Molech/Moloch(god of the Ammonites).
These gods were primarily identical with each other. They were both fire-gods. They were common to all the Canaanite, Syrian, and Arab tribes, who worshiped the destructive element under an outward symbol with most inhumane rites. According to Jewish tradition, the image of Molech/Moloch was described as brass and hollow within, a face of a calf, and his hands outstretched and open to receive(something) of his neighbor.
The worship practice of these gods would be kindled with fire and Chemerian(priest of the cult) took the babe and put it in the hands of Molech, and the babe gave up the ghost(died). This was an act of human sacrifice or ancient abortion during this time period.
The names of Chemosh and Molech mean subduer, and king. Subduer, meaning Satan's way of destroying man's seed, to suppress man's inhabitancies of the earth, and an indirect attack against G-d, by attempting to destroy G-d's creation. Molech means king or a principality. Principality in the Hebrew means mar'ashah - demon; prop. Headship, dominion. In the Greek it means arch, chief(in various applications of order, time, place or rank): beginning, corner, (at the) first(estate) magistrate, power, principle, role. Which we can see the connection of Chemosh and Molech being the prince of abortion in the Old Testament Bible.
In modern terms, the doctors that perform abortions are nothing more than your modern day Chemarian of Chemosh and Molech, who kill off a woman's fetus. As we can see in Psalm 106:35-38 states that in reality the people were really sacrificing children to devils. Ultimately behind modern day abortion clinics, and abortions, is Satan and his army of darkness.
Amplified Bible (AMP)
35 But mingled themselves with the [idolatrous] nations and learned their ways and works
36 And served their idols, which were a snare to them.
37 Yes, they sacrificed their sons and their daughters to demons
38 And shed innocent blood, even the blood of their sons and of their daughters, whom they sacrificed to the idols of Canaan; and the land was polluted with their blood.
King James Version (KJV)
12 For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
