Exodus 4:9 is God’s third and final sign for Moses, given so that the Israelites will believe that the Lord has truly sent him. If the first two miracles do not convince them, Moses is to scoop water from the Nile and pour it on dry ground, where it will turn to blood. The verse is spoken by the LORD to Moses at the burning bush, in the middle of Moses’ protest that he is not the right man for the job.
It will happen, if they will not believe even these two signs or listen to your voice, that you shall take of the water of the river, and pour it on the dry land. The water which you take out of the river will become blood on the dry land.”

What Exodus 4:9 Means
The phrase “if they will not believe even these two signs” tells us that God expects some resistance. The earlier signs were the staff that became a serpent and the hand that turned leprous and then clean again. God is not surprised by doubt. He plans for it and gives Moses a backup. The verse is an act of patience toward a fearful man and a hesitant people.
The sign itself is striking. Water drawn from the river is poured on dry land and becomes blood. The Nile was the source of life for Egypt, so a visible change in its water would be unmistakable. The verse does not promise that every skeptic will be persuaded, though. It describes what God will do if the first two signs fail. It promises that God has provided more evidence, not that belief will follow automatically.
The Context of Exodus 4:9
Exodus is traditionally attributed to Moses and tells the story of Israel’s deliverance from Egypt. Chapter 4 falls at a turning point. Moses has been called from the wilderness of Midian to return to Egypt, and he has raised objections one after another. Verses 6 through 8 describe the second sign, the hand that becomes leprous and is restored, and God’s words that the people may believe “the voice of the latter sign.” Verse 9 extends that pattern to a third sign.
Verses 10 through 12 immediately follow, where Moses complains about his speech and the LORD answers that he is the one who made the mouth and who will be with Moses to teach him what to say. Read this way, the third sign is part of a larger pattern of God meeting Moses’ fear with evidence and presence. It is not a magic trick, but a patient provision for a nervous servant.
Key Phrases in Exodus 4:9
Exodus 4:12
Now therefore go, and I will be with your mouth, and teach you what you shall speak.”
(WEB)
This verse comes right after the third sign and shows the heart of the passage. God answers Moses’ fear about his speech with a promise of his own presence and guidance. It helps us see that the signs were given to strengthen a called servant, and that the real source of Moses’ courage would be God’s ongoing companionship.
Exodus 3:12
He said, “Certainly I will be with you. This will be the token to you, that I have sent you: when you have brought the people out of Egypt, you shall serve God on this mountain.”
(WEB)
Spoken earlier at the burning bush, this verse contains God’s promise that he will be with Moses. It sets the foundation for the signs in chapter 4. Reading it alongside verse 9 reminds us that the signs were not the ground of Moses’ confidence. God’s assurance of his presence was.
A Short Prayer From Exodus 4:9
Lord, you know how easily I doubt, and how often I ask for more proof before I obey you. Thank you that you are patient with fearful people, and that you do not turn away from our weakness. Help me to trust the word you have already given me, and to step forward even when I cannot see the whole path. Be with my mouth and my hands, and teach me what to say and do. Amen.
