Moses was keeping flock of his father -in - law on mount
Answer Details
Moses was keeping flock of his father-in-law on mount Horeb. According to the Bible, Moses fled from Egypt to the land of Midian, where he married Zipporah, the daughter of Jethro. Jethro was a priest of Midian and had given Moses refuge. While in Midian, Moses tended to his father-in-law's flocks on Mount Horeb. It was on this mountain that Moses encountered the burning bush and received his call from God to lead the Israelites out of slavery in Egypt.
