Harmony

Philippians 4:2-3

2 I urge Euodia and I urge Syntyche to live in harmony in the Lord. 3 Indeed, true companion, I ask you also to help these women who have shared my struggle in the cause of the gospel, together with Clement also and the rest of my fellow workers, whose names are in the book of life.
