In the Hebrew Bible, Jethro is the name given as Moses' father-in-law, a "shepherd, and priest of Midian;" however, he is also known to some as one of the prophets in the Qur'an.
He seems also to be revered as a prophet in his own right in the Druze religion. The Druze believe that Jethro was the hidden prophet who inspired Moses, the recognized prophet. Timothy Hogan in 'Entering the Chain of Union' states that according to traditional Druze oral teaching, certain souls in antiquity came to earth (and by some accounts to Egypt in particular) and they all agreed to reincarnate until all humanity had attained Gnosis or Divine Knowledge of God. The names of these souls were then engraved on two tablets, which were then placed inside two hollow pillars – one to withstand fire and one to withstand water. According to their tradition, Jethro was one of these souls, and he initiated Moses into the tradition. Consequently, Jethro is revered by Druze as one of their greatest Prophets.
In Exodus 2:18 Moses's father-in-law is named Reuel, and this is repeated in Numbers 10:29 (where Hobab is described as Reuel's son). In the Hebrew version of Judges 4:11, Hobab is described as Moses's father-in-law, while in others as his brother-in-law.
