The Slaughterer: The Kingdom of Yishmael
The shochet, the slaughterer, refers to the first Yishmaelite king, Mohamed, who reigned in the year 374 of the fifth millennium (שע"ד). He captured the great city of Antioch and the entire Aramaic lands, as well as Armenia, their holy city, and all of Asia Minor. His reign has been a thorn in the side of the Romans to this day. He is called shochet because the gematria of the word equals “The King Mohamed, their prophet.” He is the king of Yishmael, the second of the two kingdoms of the fourth reign seen in Daniel’s vision. Another reason Yishmael is called the shochet is hinted at by the commandments that the Muslims uphold more than the other nations: ritual slaughter, circumcision, refraining from pig’s meat, and ritual immersion. The first letters of the Hebrew words for them spell shochet.
