immediately: marking that one thing follows another with no delay, from a strict instant to a simple narrative "and then"
This is an adverb of time built from the adjective meaning "straight" (εὐθύς). A straight road is the most direct route between two points, and the word carried that picture over into time: one thing following another by the shortest possible interval, with nothing in between. So at its core it means "without delay."
In practice the strength of that "without delay" slides up and down with the context. At its strongest it means a true instant, the moment the cause produces its effect, which is why the Gospel writers reach for it again and again in healing scenes: the leprosy is gone the second Jesus speaks. A step weaker, it means "promptly" or "as soon as," a short and eager interval rather than a frozen instant. Weaker still, and especially in Mark, the word can lose almost all of its timing force and work as a storyteller's hinge, simply moving the action forward: "and then," "so then," "next." And once, stretched the other direction, it means "soon" rather than "at once."
The same Greek word covers this whole range, so the senses below are shades of one idea, not different words. Which shade a given verse carries is read from the scene, not from the word by itself. This is why translations vary so widely, and why Mark in particular, who uses it more than forty times in a short book, has drawn a long debate over how much real urgency the reader is meant to feel.
Nuances
Disputed
How much temporal force the word carries in Mark, where it appears more than forty times: whether it is consistently strict immediacy, a weakened narrative connective like "and then," or a mix to be read case by case.
- contestedThe word keeps real temporal force throughout Mark; its piling-up portrays a ministry of breathless, even eschatologically urgent, activity rather than losing its vitality.; Robert H. Gundry, Mark: A Commentary on His Apology for the Cross (Eerdmans, 1993), 49-50, 75; Joel Marcus, Mark 1-8 (Anchor Yale Bible 27; Yale University Press, 2000), 165-166
- contestedEspecially when it opens a clause, the word often works as a connective or scene-marker with little or no timing force, functionally close to "and"; reading strict immediacy into every case over-exegetes what Mark did not intend to emphasize.; Rodney J. Decker, Temporal Deixis of the Greek Verb in the Gospel of Mark with Reference to Verbal Aspect (Studies in Biblical Greek 10; Peter Lang, 2001); Stanley E. Porter, Idioms of the Greek New Testament, 2nd ed. (Sheffield Academic Press, 1999), 213
- contestedThe word is a Markan stylistic signature that blends mild temporal urgency with structural scene-marking, usually introducing a new incident or a dramatic new phase, and must be read case by case.; R.
