Would you know if there is a translation into Finnish of the hymn which begins
Bless this house
O lord we pray
Make it safe
By night and day
I searched from all the Finnish library databases, but I couldn't find a translation of the hymn.
The song is composed by May Brahe and the lyrics are by Helen Taylor. I searched music databases by the composer and also by the lyricist, but there wasn't any Finnish language results. All the results were in English. The song is very popular and has been recorded by the greatest opera singers.
