One of my favorite songs to sing (with a choir) and one of my favorite songs to listen to. I love all things John Rutter! I have a recording of the Cambridge Singers singing this piece and listen to it often.
The Lord lift His countenance up on you
and give you peace, and give you peace
The Lord make His face to shine upon you
and be gracious unto you
and be gracious, and be gracious
The Lord be gracious, gracious upon you.
