What does ekballō mean?
Ekballō (ἐκβάλλω) is the Greek word the Bible uses for casting out; built from ek (“out”) and ballō (“to throw”), it means to throw out, drive out, thrust forth or expel, and Jesus uses it both for demons and for workers sent into the harvest (Matt 9:38).
It is a forceful word — not a gentle "send" but a throw, a thrust, an expulsion. The same verb that hurls demons out of the captive is the word Jesus chooses when He tells us to beg the Lord to thrust workers into His harvest.
Same verb · two missions
The harvest and the exorcism share one word: ἐκβάλλω
Built from ἐκ ("out") fused to βάλλω ("to throw"), the verb keeps that force in every use. When Jesus says to pray that the Lord would ἐκβάλῃ workers into the harvest (Matt 9:38), it is the identical word He uses to ἐκβάλλω demons (Matt 12:28) — and the word for how the Spirit ἐκβάλλει Him into the wilderness (Mark 1:12). The lemma never changes; only the form does.

The arc of the word
Seven movements of the thrusting-out
From the force first laid on Jesus, to the harvest cry, to delegated authority over demons, to the one Person He will never thrust away — the verb tells a single story when its uses are laid in order.
I
The force falls first on Jesus
Before He thrusts anyone out, the Spirit thrusts Him.
Immediately the Spirit drove Him out into the wilderness.
Mark's startling word: the Spirit does not merely lead Jesus — He thrusts Him out. The same force that will expel demons first propels the Son into the testing-place.
II
The harvest is great — beg Him to thrust out workers
Not a polite invitation to go; an urgent expulsion into the field.
The harvest is plentiful, the workers few — so beg the Lord of the harvest to thrust out workers into His harvest.
The heart of this study. Jesus does not say "send" with a soft word; He uses the exorcism verb. The Lord must almost force laborers out — because we are slow, comfortable, and reluctant to go. Prayer for missions is prayer for holy compulsion.
Pray the Lord of the harvest to thrust out workers into His harvest.
Luke records the identical command as Jesus sends the seventy. The mission verb and the deliverance verb are one: to advance the gospel is itself to drive back the dark.
III
Authority is delegated to the sent ones
Those thrust into the harvest are armed to thrust out the enemy.
If I cast out the demons by the Spirit of God, then the kingdom of God has come upon you.
The exorcism is not a sideshow. It is the evidence of the Kingdom's arrival — the strong man bound, his house plundered (Matt 12:29). Luke 11:20 says "by the finger of God."
V
In My name they will cast out
The authority outlives the Twelve; it belongs to His name.
Why could we not cast it out? … "This kind comes out only by prayer."
The same men authorized in stage III now cannot. The deficiency is not a formula but a depleted life of prayer. Power for the thrusting-out is borrowed daily.
VII
The One He will never cast out
The hand that expels demons will never expel the one who comes.
The one who comes to Me I will never, ever cast out.
The most tender use of the verb, sharpened by οὐ μή — the strongest negation in Greek, "by no means, ever." The same force that drives out the unclean is turned into an unbreakable promise of welcome.
The shadow side · expulsion as judgment
The verb of deliverance is also the verb of rejection
The same throwing-out that frees the captive can describe being slandered, driven from the synagogue, or finally shut out. Casting out demons is no proof of belonging — and the verb can run the other way.
The sons of the kingdom will be cast out into the outer darkness.
The gravest use: a passive and future form — final exclusion. The whole point of 6:37 is that those who come to Him are exempt from this.
For the careful reader
Two things worth noticing
① Why "send out" feels too soft
English versions render ἐκβάλῃ in Matt 9:38 as "send out" (NKJV, ESV, NIV) — accurate, but it can mask the force. The word literally means thrust / drive / expel. The reluctance is on our side: the Lord must press laborers out of comfort and into the field.
So the prayer of Matt 9:38 is not merely "raise up volunteers." It is "Lord, exert the kind of force on willing hearts that You exert on demons — and move us out."
②ἐκβάλλω is not the same as authority (ἐξουσία)
In Mark 3:15 the disciples are given ἐξουσία (the right, delegated authority) toἐκβάλλειν (the act of casting out). The act flows from granted authority, never from the practitioner's own resources — which is exactly why Mark 9:28–29 turns on prayer, and Matt 7:22 warns that the act alone proves nothing.
