Exodus 8:29 records Moses telling Pharaoh that he will pray for the removal of the plague of flies, but warning him not to go back on his word. The verse shows Moses agreeing to intercede for the king while holding him to the promise he has just made. It is spoken by Moses, the leader God sent to bring Israel out of Egypt, and it is addressed directly to Pharaoh, the ruler who has refused to release the Israelites.
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 by saying he is going out from Pharaoh’s presence to pray. He is not bargaining for a favor or hiding anything. He is making clear that the relief from the flies will come from the LORD, and that he is the one carrying the request to God. The timing is specific: the flies will leave “tomorrow.” Moses gives Pharaoh a concrete promise that can be checked the next day.
The second half of the verse carries the real force. Moses adds a condition: Pharaoh must not deal deceitfully by refusing to let the people go to worship. The verse does not promise that prayer automatically softens a hard heart or that God will act no matter what the king decides. It promises that God will respond to Moses’s prayer, and it calls Pharaoh to keep his word once the plague is gone.
The Context of Exodus 8:29
Exodus is traditionally attributed to Moses, and it tells how God delivered the descendants of Jacob from slavery in Egypt. The book was written for the Israelite community that had left Egypt and was preparing to enter the promised land, so it teaches them who the LORD is and what he has done for them. The plagues are part of God’s demonstration that he, not Pharaoh or the gods of Egypt, rules over creation.
In the verses just before, Pharaoh offers a partial deal: the Israelites may sacrifice, but not go far into the wilderness, and he asks Moses to pray for him. Moses insists on the full three-day journey God has commanded. In verse 29 he accepts the request to pray, yet he sets the terms. The verses after show that God does what Moses asks, yet Pharaoh hardens his heart again in verse 32. That sequence explains why the verse is not a simple promise of a changed king. It records a negotiation in which God keeps his word while the human ruler does not.

Numbers 23:19
God is not a man, that he should lie, nor a son of man, that he should repent. Has he said, and will he not do it? Or has he spoken, and will he not make it good?

This verse teaches that God does not lie and does not change his mind the way humans do. It connects with Exodus 8:29 by contrasting God’s faithfulness with Pharaoh’s broken word. The verse reminds readers that the LORD keeps his promises, which is why Moses can speak confidently about the plague’s removal.
A Short Prayer From Exodus 8:29
Lord, you hear the prayers of those who come to you in honesty, and you keep the promises you make. Help me to bring my needs to you with trust, and to pray for others even when they have let me down. Where I have been tempted to deal deceitfully, whether with you, with others, or with myself, make me willing to tell the truth and keep my word. Let my requests and my actions agree, so that I may honor you in what I say and what I do. Amen.
