ISIS, otherwise locally known as Daesh, may be the most feared terrorist organization on the planet today. But besides their unspeakable atrocities, many question the organization's origins. Now Jonathan Cahn claims that the terror group may actually have Biblical roots.

According to a report in the Christian Post, ISIS began to form during the Second Gulf War in 2003, during the U.S.-led  coalition of that invaded Iraq. ISIS is an offshoot of Islamic extremist group al-Qaida. They were reportedly led by jihadist Abu Bakr al-Baghdadi.

The group was first known as the Islamic State of Iraq (ISI), and later ISIS added the second S for Syria.

Meanwhile, Rabbi Jonathan Cahn, Messianic Jewish speaker and bestselling author, attempts to trace ISIS roots much further, Charisma News reports.

"ISIS you almost could say ... is the re-manifestation of the ancient Assyrians, I mean, down to the land," Cahn says. "Most likely, even more than al-Qaida, they literally most likely even more strongly have the blood of the Assyrians in them." 

It's no wonder then that ISIS, just like the Assyrians, are famous for mutilating their enemies. They would often display the bodies to scare people into submission, Cahn says. 

Another interesting similarity is that ISIS took over Mosul, which was the biblical site of the city of Nineveh.  Nineveh was the ancient capital of the Assyrian nation. Cahn calls these parallels as "more evil."

ISIS' atrocious conduct have drawn the ire not just of Western and non-Islamic governments, but from moderate Muslim governments as well.

The Christian Post mentions that Islamic opposition to ISIS has already come from the Indonesian government, which banned support for ISIS after the latter tried to recruit members from Indonesia.

Egyptian cleric Grand Mufti Shawqi Allam has also declared on state news agency MENA that ISIS "poses a danger to Islam and Muslims."

"[They] give an opportunity for those who seek to harm us, to destroy us and interfere in our affairs with the [pretext of a] call to fight terrorism," said Allam.

Despite ISIS having originated from the al-Qaida group, both groups are actually at odds with one another. The report points out that Al-Qaeda tactics focus on foreign enemies like the U.S. while ISIS leader Abu Bakr al-Baghdadi's tactics involve beheadings, crucifixions, and targets local regimes and rivals.
