and not by his coming only, but also by the comfort wherewith he was comforted in you, while he told us your longing, your mourning, your zeal for me; so that I rejoiced yet more.

For behold, this selfsame thing, that ye were made sorry after a godly sort, what earnest care it wrought in you, yea what clearing of yourselves, yea what indignation, yea what fear, yea what longing, yea what zeal, yea what avenging! In everything ye approved yourselves to be pure in the matter.

ἐπιπόθησιν, epipothēsin “longing,”
