Step-by-step explanation:
The Arbah Turim was written by Jacob ben Asher in the 14th century. It is a codification of Jewish law and is considered one of the main works of halacha (Jewish religious law). Jacob ben Asher was a Spanish Rabbi who lived in Toledo, and his work is still widely studied and referenced today. The Arbah Turim is divided into four sections: Orach Chayim (laws of daily life and prayer), Yoreh De'ah (laws of kosher food and other religious practices), Even Ha'ezer (laws of marriage and divorce), and Choshen Mishpat (laws of ethics and civil matters).
