When Jethro heard of this he invited Moses to be his shepherd and to live in his house. Moses accepted the home offered him, and in time married Zipporah, one of Jethro's daughters. They had two sons, one named Gershom, a word which means "stranger," and Eliezer, or "God is my help."
For the next forty years Moses led the life of a shepherd in the land of Midian, in gradual preparation for the great work he was to do later. He certainly learned patience and must have become familiar with the country through which he was to lead the children of Israel when the time of their deliverance from Egypt came. During this time the afflictions of the Israelites had been increased. Another Pharaoh ruled the land, but his reign brought no relief to the nation toiling under cruel taskmasters.
One day Moses was feeding his flocks on a mountain called Horeb, when he saw a bush of wild thorn, or acacia, apparently on fire. He looked more closely but could see no smoke, neither were the leaves and twigs blackened or consumed.
"A BUSH OF ACACIA APPARENTLY ON FIRE."
Then a Voice which seemed to come from the bush called, "Moses, Moses." Understanding that it was the Voice of God, Moses answered, "Here am I." Then God told him to come no nearer, and to take off his shoes and stand with bare feet, for His presence made the spot holy ground.
Moses tremblingly obeyed and stood with covered face while God told him that He had heard the cries and seen the affliction of the children of Israel, and that He would set them free from their bondage in Egypt. He told Moses that He had chosen him to be the deliverer of His people and their leader to the land of Canaan, which He had promised to Abraham.
Moses felt unequal to this great undertaking and tried to excuse himself on various grounds. He said that the Israelites would not listen to him unless he could, by means of signs and wonders, convince them that he was the divinely appointed leader, and he also said that he was not a ready speaker.
But God told him just what he had to do and that his brother Aaron should be his spokesman. He bestowed upon him the power to do wonderful things and promised His own protection and help. Moses could refuse no longer, and accepted the divine commission. Then the Voice ceased, the vision of the burning bush faded away, and Moses was alone again with his flocks.
When Moses returned to his home he told Jethro that he wished to go to Egypt, and in the speech of those days Jethro replied, "Go in peace." So Moses set out on his journey and on the way met his brother Aaron, whom God had sent to meet him.
