'Deep' in the Bible

We were encouraged not only by his arrival, but also by the encouragement you gave him, as he reported to us your longing, your mourning, your deep concern for me, so that I rejoiced more than ever.

For see what this very thing, this sadness as God intended, has produced in you: what eagerness, what defense of yourselves, what indignation, what alarm, what longing, what deep concern, what punishment! In everything you have proved yourselves to be innocent in this matter.
