Exodus 8:31 tells us that God did exactly what Moses asked. He took away the swarms of flies that had plagued Pharaoh, his officials, and the people of Egypt, and not a single fly was left. The verse is a record of a specific act of God in answer to a specific prayer, given within the larger story of Israel’s release from slavery.
The LORD did according to the word of Moses, and he removed the swarms of flies from Pharaoh, from his servants, and from his people. There remained not one.

What Exodus 8:31 Means
The verse begins with “The LORD did according to the word of Moses.” The phrase tells you that Moses had spoken God’s message and had prayed, and God responded by acting in line with that request. It shows a God who listens and who answers when his servant asks in faith. The writer is not describing a clever trick or a natural cycle ending. He is saying the removal of the flies was the LORD’s own doing.
Next the verse says the swarms were removed “from Pharaoh, from his servants, and from his people,” and then ends with the short line “There remained not one.” That closing sentence is the heart of the verse. The relief was complete. No pocket of the plague stayed behind to make Pharaoh think his troubles were nearly over. The verse does not say why Pharaoh would later refuse to let Israel go, and it does not promise that every prayer will end in an obvious, total victory. It records one answered request and the completeness of God’s response.
The Context of Exodus 8:31
Exodus is the second book of the Pentateuch, the first five books of the Old Testament, traditionally attributed to Moses. It tells how God brought the descendants of Jacob out of slavery in Egypt and formed them into a nation at Mount Sinai. The original audience was the people of Israel, who needed to know that the God who had made promises to their ancestors was the one who had the power to deliver them.
The verses just before this one show Pharaoh bargaining. In verse 28 he agrees to let Israel go into the wilderness to sacrifice, but only if they do not go far, and he asks Moses to pray for him. Moses agrees to pray, but he warns Pharaoh not to deal deceitfully again. The verse that follows, Exodus 8:32, shows Pharaoh hardening his heart once more and refusing to release the people. Read against that background, Exodus 8:31 is a moment of mercy and proof of God’s power that stands between a king’s broken promise and his continued defiance.
Key Phrases in Exodus 8:31
Psalm 145:18
The LORD is near to all those who call on him, to all who call on him in truth.
(WEB)
This verse says the LORD is near to all who call on him in truth. It pairs naturally with Exodus 8:31 because both show God responding to people who bring their requests to him. Moses prayed, and God acted. Psalm 145 widens that truth into a general promise of nearness to those who call.
Exodus 9:4
The LORD will make a distinction between the livestock of Israel and the livestock of Egypt; and nothing shall die of all that belongs to the children of Israel.”’”
(WEB)
In the next plague account, God makes a distinction between Egypt and Israel. This passage helps you see that the removal of the flies was part of a larger story in which God is both judge over Egypt and protector of his people. Reading it alongside Exodus 8:31 shows that God’s deliverance is ordered and purposeful, not random.
A Short Prayer From Exodus 8:31
Lord, you heard Moses when he prayed, and you answered in a way that left nothing undone. I bring you the requests I have been carrying, some of which feel heavy and unresolved. Help me to pray with the same honesty Moses showed, and to trust that you are able to act fully on my behalf. Give me patience when I cannot see your answer yet, and keep me faithful when others around me fail to keep their word. Amen.
