King James wording
King James Version
Thus saith the LORD, In this thou shalt know that I am the LORD: behold, I will smite with the rod that is in mine hand upon the waters which are in the river, and they shall be turned to blood.THE KEY
The river itself becomes the revelation: the LORD is known as its waters are overturned into blood.
THE MEANING
The verse makes knowing tangible: the LORD is recognized through an act in the world, as the river’s waters are struck and turned to blood. The transformation is violent, and the verse leaves its violence visible. What is familiar and sustaining becomes the sign.
THE ROOT
נֶהֶפְכוּ
nehephekhu
GROWS FROM
הפך
haphak
Turn, overturn, reverse.
The river does not simply change appearance; it is overturned from water into blood. The same root can describe an overthrow, giving “turned” a force English can make sound more neutral than it is.
ALSO GROWS
haphak: To turn or overturn.
הָפַךְ
This verb names the force at work in the river’s transformation.
mahpekah: Overthrow; upheaval.
מַהְפֵּכָה
This related word shows how the root can describe a change that overturns an established order.
תֵּדַע
tedaʿ
GROWS FROM
ידע
yadaʿ
Know, recognize, perceive.
“perceive” in this verse is tedaʿ. Here, knowing is recognition that comes through encounter with what is happening. The root can also describe intimate knowing, so the verse’s knowledge is more immediate than collecting a fact: the river’s change makes the claim visible.
ALSO GROWS
daʿat: Knowledge; understanding.
דַּעַת
This noun from the same root shows that knowing can become an apprehended reality, not merely a spoken claim.
yodeaʿ: One who knows or perceives.
יֹדֵעַ
This form keeps the emphasis on a perceiving subject, echoing the verse’s direct address: “thou shalt know.”
THE PATTERN
A claim becomes knowable through a visible act that discloses the one acting.
And the Egyptians will perceive that I am the LORD, when I show my weight upon the Great House, upon his chariots and upon his horsemen.Thus I will make myself great, and set myself apart; and I will be known in the eyes of many nations, and they will perceive that I am the LORD.This beginning of signs Jesus made in Cana of Galilee, and he brought his weight into the light, and his disciples leaned their weight on him.THE THREAD
And the Egyptians will perceive that I am the LORD, when I show my weight upon the Great House, upon his chariots and upon his horsemen.Both verses use ידע (yadaʿ, “know, recognize, perceive”) in the phrase “know that I am the LORD.” The repeated words connect the river’s overturning to a wider pattern in which recognition comes through what the LORD does.
