The answer is: Midian

Ex 2:15

When Moses fled to Midian after striking down the Egyptian, he embarked on a journey that transformed him from a privileged member of Pharaoh's household to a humble shepherd. It's worth delving into Midian, a region often identified with the northwestern part of modern-day Saudi Arabia, known for its rugged landscape and nomadic tribes. This desert setting provides a backdrop for essential spiritual development.

During his time in Midian, Moses encountered God—even through the unexpected medium of a burning bush! This divine moment (Exodus 3) signified a shift in his life's mission. Interestingly, Moses’ father-in-law, Jethro, is one of the notable Midianites in the story. He wasn't just a character in Moses' life but also was recognized as a priest of Midian, highlighting the diverse spiritual practices of the time, which surely contributed to the richness of Moses's character and leadership.

Moreover, the name "Midian" itself echoes throughout the Bible, later associated with various conflicts, such as when the Israelites fought against the Midianites led by Phinehas. Still, after those events, there’s also a constant reminder of reconciliation and unity. Thus, Moses's connection to Midian is woven into a broader narrative of growth, reflection, and transition as he matures into a leader who would guide a nation toward liberation and deeper understanding.
