In the Hebrew Bible, Jethro was Moses' father-in-law, a Kenite shepherd and priest of Midian, but different from Reuel. In Exodus, Moses' father-in-law is initially referred to as "Reuel" but then as "Jethro". He was also identified as Hobab in the Book of Numbers 10:29.
The relationship of the Biblical Jethro to Islam and the Druze religion is controversial. Some scholars claim that the Biblical Jethro could not have been the father/founder of the Druze religion as the Biblical Jethro lived about 1400 BCE, being somewhat older than Moses. That date greatly predates the founding of Islam related religions by thousands of years. Therefore, some scholars claim that Jethro should not be revered as the spiritual founder and chief prophet in his own right of the Druze religion and is considered an ancestor of all Druze.
It is also known that the city Yathrib was named after the Hebrew 'Yitro' who was thought to have lived there.
