Exodus 8:29 is Moses telling Pharaoh that he will pray for the removal of the swarm of flies, and that it will happen the next day. He attaches one condition: Pharaoh must stop going back on his word and let the Israelites go to worship the LORD. Moses speaks these words in the eighth plague narrative, directly to the Egyptian king, after Pharaoh has asked him to intercede.
Moses said, “Behold, I go out from you, and I will pray to the LORD that the swarms of flies may depart from Pharaoh, from his servants, and from his people, tomorrow; only don’t let Pharaoh deal deceitfully any more in not letting the people go to sacrifice to the LORD.”

What Exodus 8:29 Means
Moses begins with “Behold, I go out from you.” He is stepping away from the royal court to pray, which tells Pharaoh that the relief he wants is coming from God and not from any political bargaining. Moses does not claim the power himself. He simply reports that he will go and ask the LORD on Pharaoh’s behalf.
The verse then names the scope of the request: the flies will leave Pharaoh, his servants, and his people. The plague is not limited to the palace. Moses is also making the point that the trouble has spread through the whole nation, so the relief has to reach everyone under Pharaoh’s rule.
The final clause is the condition: “only don’t let Pharaoh deal deceitfully any more in not letting the people go to sacrifice to the LORD.” The verse does not promise that Pharaoh will keep his word. It is a warning. Relief is granted, but Pharaoh must stop breaking his promises. The verse guarantees nothing about Pharaoh’s response, and the story shows he will harden his heart again.
The Context of Exodus 8:29
Exodus is traditionally attributed to Moses, and it was written for the Israelites as they came out of Egypt and prepared to receive the law at Sinai. The book tells how God rescued a people who had been enslaved, and the plagues are the means by which he confronts Pharaoh and shows his power over Egypt’s gods and its ruler.
Just before this verse, Pharaoh agrees to let the people go into the wilderness to sacrifice, but only if they do not go very far, and he asks Moses to pray for him. Verse 29 answers that request directly. Verse 32 then shows Pharaoh hardening his heart again. Reading the verse inside that sequence makes clear that Moses’ prayer is answered and Pharaoh’s promise is broken, which is why the verse carries a warning as well as an offer of relief.

James 5:16
Confess your offenses to one another, and pray for one another, that you may be healed. The insistent prayer of a righteous person is powerfully effective.

James links prayer to righteous living and the effectiveness of a person who prays. Moses’ intercession for Pharaoh, and the honest way he speaks, match the picture of prayer that James describes.
A Short Prayer From Exodus 8:29
Lord, you hear the requests of those who come to you, and you are faithful even when the people around us are not.
