This prayer from Hebrews 13:20-21 is a benediction, a prayer that comes at the end of a letter, is spoken over someone, or said before a service finishes.
Now may the God of peace, who through the blood of the eternal covenant brought back from the dead our Lord Jesus, that great Shepherd of the sheep, equip you with everything good for doing his will, and may he work in us what is pleasing to him, through Jesus Christ, to whom be glory for ever and ever. Amen.
