King James wording
King James Version
And he said unto them, This kind can come forth by nothing, but by prayer and fasting.THE KEY
The Greek places the exit in prayer and fasting, locating release inside a posture of dependence and abstention.
THE MEANING
Where something feels beyond ordinary effort, the verse locates its opening in prayer and fasting. Release is pictured as an exit, and its setting is a posture of turning toward God and laying aside food.
WHAT THIS UNDOES
It undoes the belief that effort alone can force every entrenched thing out; here, the opening is located in prayer and fasting.
THE ROOT
ἐξελθεῖν
exelthein
GROWS FROM
ἔρχομαι (erchomai), with ἐξ-/ἐκ- (ex-/ek-, out)
ἔρχομαι means to come or go; the prefix marks movement out.
“come forth” in this verse is exelthein. The verb is to go out, with the prefix marking an exit. Its word family lets the direction change, into, out of, or through, while this verse makes the movement outward the point.
ALSO GROWS
eiserchomai: to go in, enter
εἰσέρχομαι
The shared verb root carries a different direction when paired with the prefix for inward movement.
dierchomai: to pass through
διέρχομαι
This branch keeps the same movement root while the prefix marks passage through.
προσευχή
proseuchē
GROWS FROM
εὔχομαι (euchomai), with πρός (pros, toward)
εὔχομαι means to pray, vow, or wish; πρός adds the sense of being directed toward.
The Greek word joins prayer with a turning toward. Its word family also carries the sense of a vow, showing prayer as more than words: it can name a committed orientation.
ALSO GROWS
proseuchomai: to pray
προσεύχομαι
This verbal branch names prayer as an act directed toward God.
euchē: prayer or vow
εὐχή
This related noun keeps prayer and vow in the same word family, linking speech with commitment.
νηστεία
nēsteia
GROWS FROM
νηστ-
nēst-
The word family names fasting and abstaining from food.
Fasting is defined by what is laid aside: the word family names abstention from food. Paired with prayer, the verse presents an opening through directed attention and chosen absence, a subtractive practice.
ALSO GROWS
nēsteuō: to fast
νηστεύω
The verb names the practice of abstaining that accompanies prayer in the verse.
nēstis: fasting, or one who fasts
νηστίς
This related form carries abstention into a description of the person marked by it.
THE PATTERN
Prayer with fasting accompanies the seeking of healing, direction, and communal care.
But as for me, when they are sick, my clothing is sackcloth; I bow my living soul in fasting, and my prayer returns to my own bosom.And I set my face toward the Lord God, to seek by prayer and pleas, with fasting, and sackcloth, and ashes.And when they had appointed elders for them in every assembly, and had prayed with fasting, they set them beside the Lord, upon whom they had trusted.THE THREAD
Is this not the fast I have chosen, to open the bonds of wickedness, to untie the cords of the yoke, to send the crushed away free, and to tear away every yoke?Isaiah unfolds fasting as the loosening of bonds, burdens, and yokes. That image makes the coming out in Mark tangible: fasting belongs to a movement where what holds a person is released.
