Can anyone help me out? We're getting ready for our first Jail Ministry service this next Saturday and I wanted an easy prayer chorus (acoustic guitar accompaniment.) Years ago we used to sing something "churchy" to the tune of "Edelweiss" and I've misplaced the words

Could this be it?

May the Lord, Mighty Lord, Bless and keep you forever,
Grant you peace, perfect peace, Courage in every endevour.
Lift up your eyes and see His face and His grace forever.
May the Lord, Mighty Lord, Bless and keep you forever
Amen.
