The Number Nobody Asked About

Everyone learns the number ten. Ten plagues, blood through firstborn, and then the sea closes over the army. The sages of the Mekhilta deRabbi Yishmael, the tannaitic commentary on Exodus compiled around the third century CE, looked at that tidy number and refused to accept it as the full account. They sat with the text the way an accountant sits with a ledger that does not balance, and what they found turned the splitting of the sea from an epilogue into the main event.

The man who lit the fuse was Rabbi Yosei Haglili. His question sounds almost technical until you feel its weight. How many plagues, he asked, actually struck the Egyptians at the water? Not in Egypt. At the sea. The Torah gives no count for the drowning. So Rabbi Yosei went hunting for it in the body-part language the Torah had already used.

The Finger and the Hand

Back in Egypt, when the magicians could not replicate the plague of lice and broke ranks and told Pharaoh, it is the finger of God (Exodus 8:15), they were naming the instrument. One finger. That single finger, Rabbi Yosei reasoned, had delivered all ten plagues. One finger, ten plagues.

At the sea, the Torah uses a different body part. It says Israel saw the great hand of God against Egypt (Exodus 14:31). A hand has five fingers. If one finger equals ten plagues, then five fingers equal fifty. Rabbi Yosei's conclusion: the Egyptians who drowned in the sea suffered fifty plagues. Five times what fell on Egypt.

The logic is airtight on its own terms. But it was only the first bid in an auction.

The Multiplication Rabbi Eliezer Brought

Rabbi Eliezer read the same passage and brought a different piece of evidence. Each plague in Egypt, he pointed out, actually consisted of four distinct sub-plagues. He derived this from a verse in Psalms 78, which describes God sending against Egypt a delegation of evil angels, and the Hebrew word for the delegation, mishleichat, carries a numerical weight in its syllables. Four categories of evil: fury, indignation, trouble, and a delegation of evil messengers. Four elements per plague, ten plagues in Egypt: that is forty sub-plagues in Egypt. At the sea, where the hand struck instead of the finger, the multiplier is five. Forty times five equals two hundred.

Israel stood on the far shore and looked back at what had just happened to the army that had enslaved their grandparents, and what they saw, by Rabbi Eliezer's count, was the effect of two hundred divine blows.

Rabbi Akiva's Final Bid

Then Rabbi Akiva spoke. He accepted Rabbi Eliezer's four elements but added a fifth. He read the same psalm and found not four but five distinct forces described in God's delegation against Egypt: fury, indignation, trouble, a delegation of evil messengers, and a fifth, the path of His anger. Five per plague, ten plagues: fifty in Egypt. Five times that at the sea: two hundred and fifty.

Two hundred and fifty plagues at the sea. That is the top of the auction. Rabbi Akiva's number is the one the Passover Haggadah accepted and built into the structure of the seder night, which is why to this day, when Jews pour out drops of wine at the Seder for each plague, the count the tradition honors is not merely ten but a multiplied reckoning of what it cost to break Pharaoh's grip on the world.

Why the Counting Matters

The exercise looks like mathematics, but its purpose is devotional. The sages were not trying to calculate God's power as a quantity. They were trying to prevent ingratitude by making the scale of what happened at the sea impossible to compress back into a simple story. Ten is a number people hear and file away. Two hundred and fifty is a number that stays in the body, because it forces you to imagine each blow separately.

Each plague in Egypt had been a lesson in what the God of Israel could do and what Pharaoh could not match. Each blow at the sea was a further demonstration of the same gap. And the progression from Egypt to sea, from ten to fifty to two hundred to two hundred and fifty depending on how carefully you multiply, was the sages' way of saying: you have not yet finished understanding what happened at the water. You have not counted everything. Sit down and count again.

Mekhilta Tractate Vayehi Beshalach 7:15Mekhilta DeRabbi Yishmael

Rabbi Yossi HaGlili presents one of the most famous calculations in rabbinic literature. He asks: how do we know that the Egyptians were struck with ten plagues in Egypt and fifty plagues at the sea? The proof hinges on two words, "finger" and "hand."

In Egypt, when the magicians failed to replicate the plague of lice, they told Pharaoh: "It is the finger of God" (Exodus 8:15). The plagues in Egypt were delivered by a single divine finger. At the Red Sea, however, the Torah uses a different word: "And Israel saw the great hand that the Lord used against Egypt" (Exodus 14:31). Not a finger, a hand.

The arithmetic is elegant. A hand has five fingers. If one finger produced ten plagues in Egypt, then a full hand at the sea produced five times ten, fifty plagues. The Egyptians suffered five times more punishment at the sea than they did during the entire course of the ten plagues in Egypt. What Israel experienced as ten devastating blows over the course of months in Egypt was multiplied fivefold and delivered all at once in the waters of the sea.

This calculation became so central to Jewish tradition that it was incorporated into the Passover Haggadah (non-legal rabbinic narrative), where subsequent rabbis expanded it even further, Rabbi Eliezer calculated two hundred plagues at the sea, and Rabbi Akiva reached two hundred and fifty. Rabbi Yossi HaGlili's original formula, however, remains the foundation: the sea was not merely a dramatic ending to the Exodus. It was the main event, dwarfing everything that came before it.

Rabbi Yossi raises a startling possibility about the ten plagues. The destruction at the Red Sea, he argues, was not a separate event from the plagues in Egypt, it happened simultaneously. The Egyptians who drowned at the sea were struck with the same plagues that were hitting Egyptians back in Egypt at that very moment. And both groups could see each other suffering.

His proof comes from a careful reading of a single verse. When the Egyptian soldiers at the sea cried out, "I shall flee from before Israel, for the Lord is warring for them in Egypt" (Exodus 14:25), the final words are crucial, "in Egypt." The soldiers at the sea did not say "the Lord warred for them in Egypt" in the past tense. They said the Lord "is warring" for Israel in Egypt right now, in the present. This means the plagues were active in both places at once.

Rabbi Yossi's reading transforms the entire Exodus narrative. The splitting of the sea was not the finale after the plagues had ended. It was a simultaneous operation. God was waging war on two fronts at the same moment, drowning the army at the sea while striking the homeland with fresh devastation. The Egyptians at the sea could literally see what was happening to their countrymen back in Egypt, and vice versa. The doubling of the punishment drives home a theological point: God's justice is not sequential. It is total and simultaneous, striking wherever the guilty are found.

Rabbi Akiva posed a provocative question: where do we learn that each of the ten plagues that struck Egypt was actually five plagues in one? If this calculation is correct, the Egyptians suffered not ten but fifty plagues while still in Egypt, and at the Red Sea, where the Torah says God's hand struck even harder, they endured two hundred and fifty.

This dramatic multiplication of the plagues comes from a broader rabbinic discussion in the Mekhilta about the scale of divine punishment at the sea. The sages debated how to read the verse in (Exodus 8:15) where the Egyptian magicians declare, "This is the finger of God." If a single finger produced ten plagues, then God's full hand, with five fingers, would produce fifty. And if the punishment at the sea was proportionally greater than in Egypt itself, the numbers multiply further.

Rabbi Akiva's approach is the most expansive in the debate. He argues that each plague contained multiple dimensions of suffering, not just one form of affliction but five simultaneous layers. A plague of blood was not merely water turning red. It was accompanied by additional torments: loathing, wrath, indignation, and the unleashing of destructive angels, based on (Psalms 78:49).

This teaching became famous far beyond the Mekhilta. It entered the Passover Haggadah (non-legal rabbinic narrative), where it is recited every year at the Seder table. Jews around the world repeat Rabbi Akiva's calculation on Passover night, marveling at the escalating scale of divine intervention. What begins as ten plagues in the simple reading of the Torah becomes, through Rabbi Akiva's lens, a cascade of hundreds of divine acts, each one a demonstration of God's absolute power over the mightiest empire on earth.

"And Israel saw the great hand" (Exodus 14:31) - severe deaths, deaths stranger than one another. Rabbi Yose the Galilean says: From where do you say that the Egyptians were struck in Egypt with ten plagues, and so forth. Rabbi Eliezer says: From where do you derive that every single plague that the Holy One, blessed be He, brought upon the Egyptians in Egypt consisted of four plagues, and so forth. Rabbi Akiva says: From where that every single plague consisted of five plagues, and so forth.

"And the people feared the LORD." Beforehand they were not in awe of the LORD, but here, "and the people feared the LORD." "And they believed in the LORD and in Moses His servant." If they believed in Moses, all the more so in the LORD. Then why does Scripture say "and in Moses"? To teach you that whoever believes in the shepherd of Israel is as one who believes in the One who spoke and the world came into being. Similarly you say, "And the people spoke against God and against Moses" (Numbers 21:5). If they spoke against God, all the more so against Moses - to teach you that whoever speaks against the shepherd of Israel is as one who speaks against the One who spoke and the world came into being.
