For perhaps he therefore departed for a season, that thou shouldest receive him for ever;
Philemon 1:15, King James Version

In context

14 But without thy mind would I do nothing; that thy benefit should not be as it were of necessity, but willingly.

15 For perhaps he therefore departed for a season, that thou shouldest receive him for ever;

16 Not now as a servant, but above a servant, a brother beloved, specially to me, but how much more unto thee, both in the flesh, and in the Lord?
