Exodus 4

1 Moses expresses doubt about his effectiveness, even though God told him how others would react. Christians often face the same doubt from the world. We may never be able to convince the world that we have met God, but we know in our hearts that we have. However, the world's doubts do not negate the truth. God has told us that most of the world will reject God's message, but He also told us that some would believe. We should not withhold on the account of the doubters, but witness for the sake of the seekers.
3 Moses had probably dealt with many snakes in the wilderness, but this one was large enough to frighten the hardy shepherd.
4 Do not try this at home. You should never catch a snake by its tail unless God tells you to.
6 The second sign was to be more frightful and much more personal. Moses' hand instantly developed an advanced case of an "incurable" skin disease.
7 Just as quickly, God can remove the infection.
9 The third sign was the transformation of water into blood. This would be a rather gruesome sign. The purpose of the signs was to help the Hebrews believe that God really has heard them and has come to free them out of Egypt. Why did He choose to use such frightening signs? It is commonly known that traumatic memories last longer. It is possible that God wanted to make a dramatic and permanent impression on His people.

Signs can not guarantee belief, but they can substantiate the credibility of the speaker. Furthermore, signs are not an end in themselves. They point the direction, but they are not the destination. If a person believes the sign, but does not believe the accompanying message, then they will start doubting when the signs stop.

10 Moses felt inadequate. In truth, when we rely on our own strength and skill we are truly inadequate. However, when we rely on God, all things are possible (Phil 4:13).
11 When we look at our physical limitations, we may feel that God can not use us. However, God sees past those limitations and can help us overcome them. When "whole" people look down on those who are sick or "handicapped," they show that they have lost sight of God's love and ability to work in their lives. As far as self-esteem is concerned, we should not look at our inadequacies, but at God's adequacy.
12 In one sense, Moses' lack of confidence is actually beneficial. Since Moses feels that he cannot speak up himself, he will have to rely on God to speak through him (2 Cor 12:9).
13 Finally, the truth comes out. Moses simply does not want to do what God asked of him. He would rather that anyone else be sent besides him.

Moses is afraid of rejection by his relatives. Moses is afraid for his life to face the Pharaoh. However, he is not afraid to oppose God. Anyone can see the irony in this, but how many of us have the same misplaced fears?

14 God is patient and understanding, but after appearing to Moses, reaffirming His promises, and giving him miraculous signs to perform, Moses had no "good" excuse not to do what was asked of him. However, God was still patient and provided a way for Moses to "ease into" the role of a prophet. Aaron, Moses' brother, would be the spokesman until Moses gains enough confidence to speak God's word directly to the people.

It is not said, but is probable that Moses had no contact with his family or people after he left Egypt. Thus, this "chance" reunion of Aaron and Moses was really prearranged by God who knew ahead of time that Moses would want Aaron to be his spokesman.

God would not let Moses back out of the assignment He gave him. God knew that Moses was the best person for this job, and it could be given to no other.

15 God would speak to Moses, but He would not often speak directly to Aaron. Is this "fair"? We must remember that with the great privilege of knowing God so personally comes great responsibility (James 3:1). In addition, we must remember that we all have equal access to God through prayer (Heb 4:16). And even if we never see an epiphany of God during this lifetime, we can be assured that we will know God face to face after the resurrection (1 Cor 13:12). Does this show that God "plays favorites"? No, but it does show that we all have different roles in history. Moses stands out as a man whom God chose for a very specific and powerful ministry. Nonetheless, each of us has our own "mission field." Our individual areas of work will probably not be recorded in any history book, but this does not mean it is any less important in God's eyes. If you do not feel you have an area of ministry you should ask God about it. He will help you determine when and how that ministry is to be done. Do not overlook the little ways in which you can minister to others.
17 God chooses through whom to work miracles. This is not something Moses "earned" or "practiced." It was a gift from God (1 Cor 12:4-11).
18 Moses was still dubious about his mission, so he did not disclose his real intentions to his father-in-law. Moses is respectful of Jethro. He does not demand that Jethro let him go, but asks permission. Jethro responds graciously. Moses was probably "indispensable," but Jethro would find another shepherd to tend his flocks.
19 As a further assurance, God tells Moses that those who were going to execute him for murder have themselves died. The new Pharaoh that Moses would face may have known about the murder, but does not pursue action against Moses.
20 Moses takes his family with him. A supportive family is a great blessing to any minister of God. Unfortunately, Moses would soon find that his wife was not supportive, but for now, he wants them with him.
24 We are not given much information about how this came about. God somehow bound Moses and his wife somehow found out it was because their son had not been circumcised as specified in God's covenant with Abraham. Since Moses had been appointed by God to fulfill the promise with Abraham, Moses and his family would be required to abide by the terms of the promise.
25 God's covenants with men have always been covenants of blood. While it appears that Moses' wife was disgusted with this ritual she was willing to do it for the sake of her husband. Not much more is said of this woman. I speculate that she was never supportive of her husband or God's work in their lives.
27 We don't know exactly how God told Aaron to go, but the command was simple and Aaron obeyed. Obedience to God is a prerequisite for spiritual leadership.

It is assumed that Aaron was a slave in Egypt, but the immediate circumstances of his departure from there are unknown. Aaron may have been a runaway slave. In many cultures runaway slaves were subject to harsh punishments, but Aaron would later return to essentially ask that all the slaves be set free.

28 God did not tell Aaron why he was to find Moses or what was about to happen, so Moses had to tell him.
31 The people believed Moses, just as God had promised. They were amazed and filled with hope. Their response of worship was very appropriate.
