Verse: Exodus 8:29
Theme: The Fourth Plague of Flies: Moses’ Warning Against Deception and the Call for Genuine Commitment
“And 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. But let not Pharaoh deal deceitfully anymore in not letting the people go to sacrifice to the Lord.'”
— Exodus 8:29, New King James Version (NKJV)
“Moses answered, ‘As soon as I leave you, I will pray to the Lord, and tomorrow the flies will leave Pharaoh and his officials and his people. Only be sure that Pharaoh does not act deceitfully again by not letting the people go to offer sacrifices to the Lord.'”
— Exodus 8:29, New International Version (NIV)
“Then Moses said, ‘Behold, I am going out from you, and I will make supplication to the Lord that the swarms of flies may depart from Pharaoh, from his servants, and from his people tomorrow; only do not let Pharaoh deal falsely again by not letting the people go to sacrifice to the Lord.'”
— Exodus 8:29, New American Standard Bible (NASB)
“Moses said, ‘I’m leaving you now, and I’ll pray to the Lord. Tomorrow the flies will go away from you, your officials, and your people. But don’t deceive us again, Pharaoh. Let the people go to sacrifice to the Lord.'”
— Exodus 8:29, God’s Word Translation (GW)
Meaning of Exodus 8:29
You know that moment when someone breaks a promise and you’re standing there thinking, “Really? We’re doing this again?” Moses finds himself in exactly that position here, and he’s not having it. He’s basically telling Pharaoh, “Look, I’ll handle my part of the bargain, but if you try to pull another fast one on us, we’re going to have problems.”
This isn’t Moses being pessimistic; it’s Moses being realistic. He’s dealt with Pharaoh’s pattern of behavior long enough to recognize the signs. Promise under pressure, renege when the pressure’s off. It’s as predictable as sunrise, and Moses has learned to call it out before it happens. There’s something deeply practical about this approach, calling out potential deception before it occurs rather than acting surprised when it inevitably unfolds.
What fascinates me about this exchange is the combination of faith and firmness. Moses demonstrates complete confidence in God’s ability to remove the flies (notice he doesn’t say “if the Lord answers my prayer” but “the flies will depart tomorrow”), while simultaneously setting clear expectations about human integrity. He’s operating from a position of spiritual strength while maintaining realistic expectations about human nature.
The warning itself is beautifully direct. No diplomatic sugar-coating, no political maneuvering. Just straight talk: “Don’t lie to us again.” It’s refreshing in a world where we often dance around uncomfortable truths instead of addressing them head-on. Moses understands that genuine relationships, even adversarial ones, require honest communication about behavior patterns and expectations.
This moment also reveals something profound about spiritual authority. Moses isn’t just performing miracles; he’s establishing standards for how people interact with both divine power and human commitment. He’s saying that supernatural intervention deserves an authentic response, not calculated manipulation.

Explaining the Context of Exodus 8:29
This passage occurs at the conclusion of the fourth plague negotiation, where Moses secures Pharaoh’s agreement while simultaneously addressing the pattern of broken promises that has characterized their previous interactions.
Moses’ warning about deception comes from experience with Pharaoh’s behavior pattern: making concessions under pressure only to reverse them once the immediate crisis passes, showing the importance of addressing established patterns of unreliability.
The mention of tomorrow’s deliverance demonstrates Moses’ complete confidence in divine power while establishing a specific timeline that will test both God’s faithfulness and Pharaoh’s integrity simultaneously.
This moment represents a crucial shift where Moses moves from simply performing miracles to establishing expectations for honest engagement, showing how spiritual authority includes the responsibility to call out deceptive behavior.
The direct confrontation about deceit reveals Moses’s growth as a leader who no longer hesitates to address uncomfortable truths, even with powerful adversaries who could make life difficult for him and his people.
Explaining the Key Parts of Exodus 8:29
“Behold, I go out from you, and I will pray to the Lord”
Moses’ confident declaration shows his complete trust in divine responsiveness to intercession, speaking with the assurance of someone who has experienced consistent divine faithfulness in previous encounters.
The formal announcement of his departure creates a clear transition from negotiation to spiritual action, showing proper respect for the prayer process while maintaining authority in the relationship dynamic.
“that the swarms of flies may depart from Pharaoh, from his servants, and from his people tomorrow”
The specific timeline demonstrates Moses’ absolute confidence in God’s power and timing, making a public commitment that could be easily verified or proven false by the next day.
The comprehensive mention of Pharaoh, servants, and people shows divine mercy extending to all levels of Egyptian society, not just the leadership who made the decisions or bore primary responsibility.
“But let not Pharaoh deal deceitfully anymore”
This confrontation about established patterns of deception shows Moses’ willingness to address uncomfortable truths rather than pretending previous betrayals didn’t happen or hoping for different behavior.
The word “anymore” acknowledges that deception has already occurred, making it clear that Moses is operating from experience rather than suspicion, and establishing accountability for future actions.
“in not letting the people go to sacrifice to the Lord”
Moses frames the potential deception in terms of preventing proper worship, showing that broken promises to human leaders ultimately represent dishonesty toward divine authority and spiritual obligations.
The specific reference to sacrifice emphasizes that this isn’t just about political freedom but about fulfilling religious duties, making Pharaoh’s potential deception an offense against both human and divine authority.
