“I sent him therefore the more carefully, that, when ye see him again, ye may rejoice, and that I may be the less sorrowful.”
King James Version (KJV)
2:28 That I may be the less sorrowful - When I know you are rejoicing.
Php 2:28 I sent him therefore the more carefully. "The more diligently" (Revised Version). Because his brethren at home were so anxious about him. That, when ye see him again, ye may rejoice. Their joy in seeing him will be a joy to Paul also, so that he will be the less sorrowful over his absence.
