Exodus 4:9

This chapter, I. Continues and concludes God's discourse with Moses at the bush concerning this great affair of bringing Israel out of Egypt. 1. Moses objects the people's unbelief (Exo 4:1), and God answers that objection by giving him a power to work miracles, (1.) To turn his rod into a serpent, and then into a rod again (Exo 4:2-5). (2.) To make his hand leprous, and then whole again (Exo 4:6-8). (3.) To turn the water into blood (Exo 4:9). 2. Moses objects his own slowness of speech (Exo 4:10), and begs to be excused (Exo 4:13); but God answers this objection, (1.) By promising him his presence (Exo 4:11, Exo 4:12). (2.) By joining Aaron in commission with him (Exo 4:14-16). (3.) By putting an honour upon the very staff in his hand (Exo 4:17). II. It begins Moses's execution of his commission. 1. He obtains leave of his father-in-law to return into Egypt (Exo 4:18). 2. He receives further instructions and encouragements from God (Exo 4:19, Exo 4:21-23). 3. He hastens his departure, and takes his family with him (Exo 4:20). 4. He meets with some difficulty in the way about the circumcising of his son (Exo 4:24-26). 5. He has the satisfaction of meeting his brother Aaron (Exo 4:27, Exo 4:28). 6. He produces his commission before the elders of Israel, to their great joy (Exo 4:29-31). And thus the wheels were set a going towards that great deliverance.

4:9 As with the previous two signs, the fact that the water from the Nile will turn to blood also demonstrated God’s power over life and death.
