'Zeal' in the Bible

and not only by his coming, but also by the comfort [with] which he was comforted among you, [because he] reported to us your longing, your mourning, your zeal for me, so that I rejoiced even more.

For behold how much diligence this very [thing], being grieved according to [the will of] God, has brought about in you: what defense [of yourselves], what indignation, what fear, what longing, what zeal, what punishment! In everything you have demonstrated yourselves to be innocent in this matter.

because I know your readiness [to help], [concerning] which I keep on boasting to the Macedonians about you, that Achaia has been ready [to help] since last year, and your zeal has stirred up the majority [of them].
