King James wording

King James Version

And smote all the firstborn in Egypt; the chief of their strength in the tabernacles of Ham:

THE KEY

The firstborn and “the chief of their strength” converge on one image: the first emergence of a household’s vigor.

THE MEANING

This verse confronts you with every firstborn struck in Mitzrayim (⁨מִצְרַיִם⁩, Mitsrayim, “the two narrows”), naming them as the first emergence of a household’s vigor. It leaves the violence exposed: the blow reaches households at the point where their strength and future are gathered.

THE ROOT

בְּכוֹר

bekhor

GROWS FROM

בכר

b-k-r

To be first or to bring forth first.

The firstborn is connected to first produce, so the verse’s violence reaches what is pictured as a household’s first issue of life. The next phrase repeats that firstness by calling them the beginning of Egypt’s vigor.

ALSO GROWS

bikkurim: Firstfruits, the first produce.

בִּכּוּרִים

This branch makes the firstborn’s place in the verse vivid: they are the household’s first issue, like the first produce of a field.

bekhorah: Firstborn status or birthright.

בְּכוֹרָה

The birthright ties firstness to a household’s identity and future, deepening what is at stake in the blow.

רֵאשִׁית

reshit

GROWS FROM

ראש

Head, beginning, or foremost point.

“firstfruits” in this verse is reshit. The phrase ⁨רֵאשִׁית אוֹנִים⁩ (reshit onim, “beginning of vigor”) makes the firstborn more than the eldest: they stand for the first emergence of a household’s strength. English separates “firstborn” from “chief,” while the Hebrew repeats the language of firstness.

ALSO GROWS

rosh: Head or foremost part.

רֹאשׁ

This branch shows the sense of “chief” as what stands at the head or forefront.

bereshit: At the beginning.

בְּרֵאשִׁית

This branch carries the same beginning sense that links “chief of their strength” to the firstborn.

THE PATTERN

Scripture concentrates a household’s beginning, strength, or identity in the firstborn.

And it came to be that at midnight the LORD struck down all the firstborn in the land of Egypt, from the firstborn of the Great House who settled on his throne to the firstborn of the captive who was in the pit, and all the firstborn of the cattle.

Exodus 12:29 · SDVThe strike reaches every firstborn from Pharaoh’s house to the captive’s, exposing how much the household’s order and future rest on them.

And you will say to Pharaoh, Thus says the LORD, Israel is my son, even my firstborn.

Exodus 4:22 · SDV“Firstborn” names Israel’s identity and relation, extending the word beyond birth order.

By trust he made the passover and the pouring of the blood, so that the destroyer of the firstborn would not touch them.

Hebrews 11:28 · SDVThe firstborn remain the lives at stake in the Passover, keeping the violence of the verse present in the passage’s retelling.

THE THREAD

Reuben, you are my firstborn, my might, the first of my vigor, the surplus of lifting, and the surplus of strength.

Genesis 49:3 · SDV

Genesis uses the same Hebrew word for “firstborn” and pairs it with “the beginning of my strength.” That pairing opens Psalm 78:51: its “chief of their strength” names the firstborn as the beginning of a household’s vigor.
