This is the final blessing. Good News Translation translates the most likely text. Some manuscripts, followed by Biblia Dios Habla Hoy, Moffatt, Knox, and older translations, add “Amen.” Others replace you with “the saints.” On grace, see comments on 4.16. God’s is implied. May God’s grace be with you all may be rendered as “May God be good to you all.” Or, as in the form of a prayer, “I pray that God may be good to you all,” or “… show you his loving kindness,” or “… demonstrate to you his love and kindness.”
