Geh' aus, mein Herz, und suche Freud
(Paul Gerhardt 1653)
Gå ut, min själ, och gläd dig...
Go out, my soul, and seek joy
German hymn from 1653; first translated into Swedish in 1725; still one of our most beloved summer hymns in Sweden. (The lyrics are basically on the same theme as How Great Thou Art, which is probably better known to most of my readers here.)
♫ Listen to a choir singing it at YouTube ♫
