Key Verses: Exodus 4:12, 4:22, 4:25
Moses objects that the people will not believe the LORD has appeared to him, so God gives three signs: his staff becomes a serpent and returns to a staff, his hand becomes leprous and is restored, and water from the Nile will turn to blood on the ground. Still Moses protests that he is not eloquent but “slow of speech and of tongue.” The LORD reminds him that He made man’s mouth and promises, “I will be with your mouth and teach you what you shall speak.” When Moses begs God to send someone else, the LORD’s anger burns, yet He graciously appoints Aaron as his spokesman. Moses returns to Jethro, and God tells him those who sought his life are dead, also instructing him to warn Pharaoh that Israel is the LORD’s firstborn son and that God will slay Pharaoh’s firstborn if he refuses to let Israel go. On the way, at a lodging place, the LORD seeks to put Moses to death, and Zipporah swiftly circumcises their son, touching Moses’ feet with the foreskin and calling him a “bridegroom of blood,” so the LORD lets him alone. Aaron meets Moses at the mountain of God, and Moses tells him all. Together they gather the elders of Israel, Aaron speaks the words, the signs are performed, and the people believe; when they hear that the LORD has visited them and seen their affliction, they bow their heads and worship.
This chapter reveals both the patience and the holiness of God in dealing with His reluctant servant. Moses’ repeated objections expose the human tendency to trust our own limitations more than God’s power, yet the LORD answers each excuse with a promise of His enabling presence, teaching that the call of God carries the equipping of God. The strange episode of the “bridegroom of blood” underscores that even the deliverer must not neglect the covenant sign of circumcision; God’s chosen leader is not above obedience, and blood must be shed to avert judgment, pointing toward the necessity of atonement. The designation of Israel as God’s “firstborn son” establishes the covenant relationship and anticipates the climactic tenth plague and, ultimately, Christ the true firstborn Son whose blood shields His people from death. As the shed blood of a son averts God’s wrath at the lodging place, so the blood of the Lamb will mark the doorposts and, finally, the cross. The people’s worship at hearing God has seen their affliction models the response of faith to the good news of divine visitation.
