Exodus 9:18 is God announcing, through Moses, that a hailstorm of unprecedented severity will strike Egypt at a set time the next day. The verse is a warning and a demonstration: God is telling Pharaoh exactly what will happen so that the coming disaster cannot be mistaken for chance. Moses speaks these words to Pharaoh, the king of Egypt, as part of the escalating series of plagues recorded in Exodus 7 through 12.
Behold, tomorrow about this time I will cause it to rain a very grievous hail, such as has not been in Egypt since the day it was founded even until now.

What Exodus 9:18 Means
The phrase “tomorrow about this time” tells us God is giving Pharaoh a specific timetable. Nothing vague is being promised or threatened. The hail will come at a stated hour on a stated day, which removes any doubt about whether it was a natural event or a divine act. God is signaling that he is in control of the timing as well as the outcome.
“A very grievous hail, such as has not been in Egypt since the day it was founded” stresses how severe the storm will be. The comparison to Egypt’s entire history is deliberate. This is not an ordinary storm that happens to hit a farming region. It is unlike anything Egypt has ever experienced, which tells Pharaoh that the God of Israel has power beyond the natural order that Egypt’s own gods were supposed to govern.
The verse does not promise comfort or protection to Egypt, and it does not describe the hail as a punishment for personal sin in a general sense. It announces a judgment tied to Pharaoh’s refusal to release the Israelites. Verse 16 of the same passage explains the purpose behind it: to show Pharaoh God’s power and to make his name known across the earth.
The Context of Exodus 9:18
Exodus is traditionally attributed to Moses and forms the second book of the Torah, the first five books of the Hebrew Bible. Its primary audience is the people of Israel, who are shaped by these accounts of their deliverance from slavery. The plagues narrative is written so that Israel, and later readers, see that their liberation was accomplished by God’s direct intervention rather than by human strength or political maneuvering.
Just before verse 18, God says that he could have destroyed Pharaoh and his people with pestilence, but has allowed them to stand so his power would be displayed. Just after, in verses 19 through 21, Moses instructs the Egyptians to bring their livestock and servants indoors. Some heed the warning and some do not. Read in this setting, verse 18 is the hinge of a moment of choice: God announces the coming judgment, and the response of individuals shows whether they take God’s word seriously.
Key Phrases in Exodus 9:18
Exodus 9:20
Those who feared the LORD’s word among the servants of Pharaoh made their servants and their livestock flee into the houses.

Verse 20 shows the Egyptians who feared the Lord’s word and acted on it immediately. Reading it beside verse 18 reveals that the same warning produced two different responses, and it highlights the difference that reverence for God’s word makes in practical choices.
Psalm 33:9
For he spoke, and it was done. He commanded, and it stood firm.

This psalm celebrates the power of God’s spoken word, which brings things into being and holds them in place. It helps explain why the hail announced in Exodus 9:18 happens exactly as God says, since his word carries the authority to accomplish what it declares.
A Short Prayer From Exodus 9:18
