Exodus 8:31 tells us that God answered Moses’ prayer exactly as he had asked. The swarm of flies that had plagued Egypt was removed from Pharaoh, his officials, and his people, and not a single fly was left behind. The verse is a short report of a miracle, and it shows that the LORD takes a prayer seriously even when the one praying is a man under pressure. Moses, speaking for the LORD, spoke to Pharaoh, and then Moses prayed to the LORD on Pharaoh’s behalf.
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 phrase “The LORD did according to the word of Moses” means that the outcome matched what Moses had asked for. Moses did not work the miracle himself. He asked God to act, and God acted in the way Moses had said he would. The verse presents a simple pattern: a request brought to God, and an answer that follows the request.
The second part, “he removed the swarms of flies from Pharaoh, from his servants, and from his people,” describes the scope of the relief. The flies were gone from the palace, from the court, and from the ordinary households of Egypt alike. The last line, “There remained not one,” stresses how complete the removal was. The verse does not promise that every hard situation will end this way, nor that God will always do what a leader asks. It records one clear case in which God answered fully and visibly.
The Context of Exodus 8:31
Exodus is traditionally attributed to Moses and tells of Israel’s rescue from slavery in Egypt, the covenant at Sinai, and the building of the tabernacle. Its first audience was the people of Israel, who needed to understand that the LORD had the power to free them from Pharaoh. The plague narratives show that God was dealing with Egypt’s false claims of power while keeping his promises to his people.
Just before this verse, in Exodus 8:28-30, Pharaoh agrees to let the people go into the wilderness to sacrifice, then asks Moses to pray for him. Moses agrees to pray and warns Pharaoh not to deal deceitfully again. Verse 31 then shows God answering that prayer. Verse 32 follows with Pharaoh hardening his heart and refusing to let the people leave. Read between these verses, 8:31 is not a story about Pharaoh being won over. It is a demonstration that God hears the prayers of his servant, even when the king who asked for mercy does not keep his word.
