The Burning Bush
God explained that he had seen how miserable his chosen people, the Hebrews, were in Egypt, where they were being held as slaves. God had come down from heaven to rescue them. He picked Moses to carry out that task.
Moses was terrified. He told God he was not capable of such a huge undertaking. God assured Moses he would be with him. At that point, Moses asked God his name, so he could tell the Israelites who sent him.
God replied, "I AM WHO I AM. This is what you are to say to the Israelites: 'I AM has sent me to you.'" God also said to Moses, "Say to the Israelites, 'The LORD, the God of your fathers—the God of Abraham, Isaac & Jacob has sent me to you. This is my name forever, the name you shall call me from generation to generation"
Then God revealed that he would perform miracles to force the king of Egypt to let the enslaved Israelites go. To show his power, the Lord turned Moses' staff into a snake, and back into a staff, and made Moses' hand white with leprosy, then healed it. God instructed Moses to use those signs to prove to the Hebrews that God truly was with Moses.
Still afraid, Moses complained that he could not speak well. God was angry with Moses' lack of faith, but promised Moses that his brother Aaron would join him and speak for him. Moses would tell Aaron what to say.
After saying goodbye to his father-in-law, Moses met Aaron in the desert. Together they went back to Goshen, in Egypt, where the Jews were slaves. Aaron explained to the elders how God was going to free the people, and Moses showed them the signs. Overcome that the Lord had heard their prayers, the elders bowed down and worshiped God.
