to throw yourself into something and not put it off: to make every effort, and to make it now
Almost every time this verb appears, it is an instruction. Paul tells Timothy to do it, Peter tells his readers to do it, and the writer of Hebrews puts himself inside the appeal by saying "let us." That shape matters. The word does not describe a temperament some people happen to have; it names something a person is asked to go and do.
Two things are packed into it: real effort, and no delay. Which one comes forward depends on what follows. When the thing to be done is a duty, the effort leads, and English reaches for "make every effort," "be diligent," or "do your best." When the thing to be done is a journey, the promptness leads, and English reaches for "hurry" or "come quickly." It is one word doing one job in both: apply yourself, and start now.
It belongs to a small family of words. The noun (σπουδή) is the eagerness or the haste itself, the adjective (σπουδαῖος) describes a person as earnest, and the older verb for plain hurrying (σπεύδω) stays with speed of movement. Among them, this is the one that presses a request or a command home.
Two neighboring words mark its edges:
- To struggle in a contest (ἀγωνίζομαι) pictures an opponent and a fight to be won.
- To labor to the point of exhaustion (κοπιάω) names the toil and what it costs the worker.
This verb names neither the fight nor the fatigue. It names the willing energy a person brings, and the refusal to leave the thing for later.
