This verse in the King James

King James wording
And they thirsted not when he led them through the deserts: he caused the waters to flow out of the rock for them: he clave the rock also, and the waters gushed out.

What looks like the hardest obstruction can become the very place from which water flows.

He leads you through the dry stretch without leaving you to thirst; water issues from the rock as it opens. The terrain that seems to deny life becomes the place where provision emerges.

WHAT THIS UNDOES

The lie this dissolves is that a hard, barren stretch proves that life has no source there.

וַיִּזֹּבוּ

vayyizzōvū

GROWS FROM

זוב

to flow, run, or issue forth

“gushed out” in this verse is vayyizzōvū. The verse ends with movement: the waters issue out from the opened rock. This root also names bodily flow, so its focus is the act of something flowing forth, not only the substance that flows.

ALSO GROWS

lāzūv: to flow, run, or issue forth

לָזוּב

The infinitive names the same outward movement that the waters enact here.

zōvō: his flow or discharge

זֹבוֹ

This form appears in language for bodily flow, showing that the same root can name water issuing from rock or fluid issuing from the body.

בָּקַע

bāqaʿ

GROWS FROM

בקע

to split or cleave open

The rock does not merely stand beside the water; it is opened as the water comes forth. The related word for a valley or cleft carries that same image of a split in the land.

ALSO GROWS

ləvaqqēaʿ: to split or cleave open

לְבַקֵּעַ

It names the same act of opening expressed by “clave.”

biqʿāh: a valley or cleft

בִּקְעָה

A cleft in the landscape carries the root’s image of an opening in what had been whole.

צָמְאוּ

tsāmeʾū

GROWS FROM

צמא

to thirst or be thirsty

“thirsted” in this verse is tsāmeʾū. The verse names the condition that does not overtake them as they travel through dry country. The same root can name thirst itself and the drought that intensifies it, keeping the provision tied to the need it meets.

ALSO GROWS

tsāmēʾ: thirsty

צָמֵא

It names the state the verse says they do not enter.

tsimmāʾōn: thirst or drought

צִמָּאוֹן

This form connects thirst with the surrounding dryness through which he leads them.

Life-giving water can issue from what appears closed, dry, or barren.

Look, I will stand before you there on the rock in Horeb. You will strike the rock, and waters will come out of it, that the people may drink. And Moses did so before the eyes of the elders of Israel.
Exodus 17:6 · SDVWater comes from a rock when it is struck, making the apparent barrier the source of what sustains life.
He brought out trickles from the cliff, and made waters run down like rivers.
Psalm 78:16 · SDVThe rock releases not a drop alone but streams that run like rivers.
The one who leans his weight into me, as the writing has said, rivers of living waters will flow from his belly.
John 7:38 · SDVThe image shifts inward, with rivers of living water flowing from within.
Speak to the children of Israel, and say to them, When any man flows out of his flesh, by his flow he is soiled.
Leviticus 15:2 · SDV

The Hebrew behind “running issue” comes from ⁨זוב⁩, the same root rendered “gushed out” here. The root names the flow itself, whether it issues from the body or from the rock.
