Moses heard the voice of God at several points throughout his life, but the most significant and foundational instance was at
Mount Horeb (also known as Mount Sinai). Here's a breakdown:
* The Burning Bush: This is the first and most well-known instance (Exodus 3). While tending his father-in-law's sheep, Moses saw a bush that was on fire but not consumed. God spoke to him from the bush, revealing His name ("I AM THAT I AM") and commissioning Moses to lead the Israelites out of Egypt.
* Mount Sinai/Horeb (after the Exodus): After leading the Israelites out of Egypt, Moses led them to Mount Sinai (Exodus 19-20). Here, God spoke to the entire nation (although the people were afraid and asked Moses to be the intermediary). God then spoke to Moses on the mountain where he received the Ten Commandments and other laws. This involved multiple encounters over a period of time (40 days and nights on the mountain).
* Later Encounters: Moses had further conversations with God throughout the Israelites' journey, seeking guidance and interceding on their behalf. These encounters are described in various parts of the books of Exodus, Leviticus, Numbers, and Deuteronomy.
So, while Moses heard God's voice at various times, the most important and foundational instances were:
* At the Burning Bush (Mount Horeb): when he was commissioned.
* At Mount Sinai/Horeb (after the Exodus): when the Ten Commandments were given and the covenant with Israel was established.
